opentui(v6): double-click word / triple-click line selection with held drag-extend

Editor-grade mouse selection parity with the Ink TUI (hermes-ink selection.ts):
a second click in the 500ms/1-cell chain selects the same-class character run
under the cursor (iTerm2 word set, wide-glyph aware), a third selects the line,
and dragging with the button held extends word-by-word / line-by-line while the
clicked span stays selected — anchor flips across the span on direction change.

Core knows only press-drag char selection, so this is a boundary shim
(multiClickSelect.ts) wrapping the renderer's startSelection/updateSelection
seam; word bounds read the presented frame's char grid. Native quirks probed
and pinned: per-renderable selection anchors are fixed at set time (anchor
flips restart the selection) and forward selections exclude the focus cell
(inclusive spans seed focus at hi+1). Pure scanning logic in logic/multiClick.ts;
20 new tests (pure + real-mouse-path frames); demo.tsx installs the seam for
tmux smokes.

 Hermes has two entry points: start the terminal UI with `hermes`, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.
 
+> **TUI engine:** On supported hosts (Linux/macOS with Node 26.3+), the terminal UI defaults to the native **OpenTUI** engine, which the installer provisions for you. The legacy **Ink** engine remains the fallback — it's used automatically on Windows, Termux, or when the native engine can't run, and you can select it explicitly with `HERMES_TUI_ENGINE=ink hermes`. Ink is not going away; it's the kept fallback.

+
+اگر آپ کے پاس پہلے سے گٹ (Git) انسٹال ہے، تو انسٹالر اسے شناخت کر لیتا ہے اور اسے ہی استعمال کرتا ہے۔ بصورت دیگر آپ کو صرف ~45MB کے MinGit ڈاؤنلوڈ کی ضرورت ہوگی — یہ آپ کے سسٹم کے گٹ پر کوئی اثر نہیں ڈالے گا۔

+آپ اب بھی کسی بھی ٹول کے لیے اپنی مرضی کی API کیز استعمال کر سکتے ہیں — گیٹ وے ہر سروس کے لیے الگ الگ کام کرتا ہے، ایسا نہیں کہ یا تو سب کچھ استعمال کریں یا کچھ بھی نہیں۔

+
+اگر آپ OpenClaw سے منتقل ہو رہے ہیں، تو ہرمیس آپ کی سیٹنگز، یادیں (memories)، مہارتیں (skills)، اور API کیز کو خود بخود امپورٹ کر سکتا ہے۔
+
+**پہلی بار سیٹ اپ کے دوران:** سیٹ اپ وزرڈ (`hermes setup`) خود بخود `~/.openclaw` کو پہچان لیتا ہے اور کنفیگریشن شروع ہونے سے پہلے مائیگریٹ (migrate) کرنے کا آپشن دیتا ہے۔
+
+**انسٹالیشن کے بعد کسی بھی وقت:**
+
+<div dir="ltr">
+
+```bash
+hermes claw migrate              # انٹرایکٹو مائیگریشن (مکمل پری سیٹ)
+hermes claw migrate --dry-run    # جائزہ لیں کہ کیا کیا مائیگریٹ ہوگا
+hermes claw migrate --preset user-data   # حساس معلومات (secrets) کے بغیر مائیگریٹ کریں
+hermes claw migrate --overwrite  # موجودہ متصادم فائلوں کو اوور رائٹ کریں
+```
+
+</div>
+
+جو چیزیں امپورٹ ہوتی ہیں:

+
+تمام آپشنز دیکھنے کے لیے `hermes claw migrate --help` استعمال کریں، یا انٹرایکٹو ایجنٹ کی مدد سے مائیگریٹ کرنے کے لیے `openclaw-migration` سکل کا استعمال کریں (جس میں ڈرائی رن (dry-run) پریویوز شامل ہیں)۔

+"""Per-turn setup for ``run_conversation`` (the turn prologue).
+
+``run_conversation`` opened with ~470 lines of straight-line setup before the
+tool-calling loop ever started: stdio guarding, runtime-main wiring, retry-counter
+resets, user-message sanitization, todo/nudge-counter hydration, system-prompt
+restore-or-build, crash-resilience persistence, preflight context compression, the
+``pre_llm_call`` plugin hook, and external-memory prefetch.
+
+All of that is *prologue* — it runs once per turn, has no back-references into the
+loop, and produces a fixed set of values the loop then consumes. ``TurnContext``
+captures those produced values; ``build_turn_context`` performs the setup work and
+returns one. ``run_conversation`` is left to unpack the context and run the loop,
+shrinking the orchestrator by the full prologue.
+
+The builder still mutates ``agent`` heavily (counters, thread id, cached prompt,
+session DB) exactly as the inline code did — those side effects are the point. The
+``TurnContext`` it returns carries only the *locals* the loop reads back.
+
+Behavior is identical to the original inline prologue; this is a pure
+move-and-name refactor with no semantic change.

+"""Per-attempt recovery bookkeeping for the conversation turn loop.
+
+The inner retry loop in ``run_conversation`` (``while retry_count <
+max_retries``) makes several distinct recovery attempts on a single model API
+call: a credential-pool 429 retry, a per-provider OAuth refresh (codex,
+anthropic, nous, copilot), a long-context compression restart, a length-
+continuation restart, and a handful of format-recovery branches (thinking-
+signature stripping, multimodal-tool-content stripping, llama.cpp grammar
+fallback, image shrink, invalid-encrypted-content, 1M-beta header).
+
+Each of those branches is guarded by a one-shot boolean so it fires at most
+once per attempt. They used to be ~16 bare ``*_attempted`` / ``has_retried_*``
+/ ``restart_with_*`` locals declared inline before the loop and threaded
+through its 2,400-line body. ``TurnRetryState`` collapses them into one object
+the loop mutates in place (``state.codex_auth_retry_attempted = True``), giving
+the recovery bookkeeping a single named, testable home.
+
+Loop-control variables (``retry_count``, ``max_retries``,
+``max_compression_attempts``) intentionally stay as plain locals — they are the
+``while`` mechanics, not recovery bookkeeping, and putting them on the object
+would add indirection without clarifying anything.
+
+This module is dependency-free so it can be unit-tested in isolation and
+imported by the turn loop without an import cycle.

+# TUI benchmark suite — Ink (`ui-tui`) vs OpenTUI (`ui-opentui`)
+
+Methodology (settled, binding): `docs/plans/opentui-bench-suite.md`. This
+directory is the implementation: real binaries over a real node-pty PTY
+(120×40, xterm-256color), a fake gateway substituted via `HERMES_PYTHON`
+(ZERO changes to either UI), external `/proc` sampling, cgroup-v2 memory caps.
+No tmux anywhere in measurement — except the `pipeline` cell, whose entire
+point is measuring the tmux emulator leg (see its note below).
+
+## Pieces
+
+| file | role |
+|---|---|
+| `fake-gateway.mjs` | NDJSON JSON-RPC gateway stand-in. Both UIs spawn it as `$HERMES_PYTHON -m tui_gateway.entry`. Answers every startup RPC with canned results, then streams the fixture (burst / paced / load-then-idle). Never writes stderr (the UIs render gateway stderr). |
+| `fixture-stream.mjs` | Serializes the deterministic lumpy-turn fixture (`ui-opentui/scripts/fixture.ts`, imported directly via Node ≥26 type stripping — no port) to NDJSON. Cached under `.cache/`, sha256-stamped. |
+| `harness.mjs` | One scenario = one UI boot: node-pty PTY, tight drain loop (event-loop starvation probe, 10ms budget asserted), `/proc/PID/{smaps_rollup,status,stat}` samples on 100-msg boundaries (UI PID only), `systemd-run --user --scope -p MemoryMax=… -p MemorySwapMax=0` caps, SGR wheel injection, resize-jiggle digest capture. |
+| `run.mjs` | The matrix runner (protocol: determinism gate first, sequential SUTs, randomized per-rep config order, 10s cooldowns, load gate). |
+| `render.mjs` | `results/*.json` → self-contained `report.html` (inline SVG, no CDN) + PNGs in `report-assets/`. |
+
+## Running cells
+
+Node 26 is required (`BENCH_NODE_BIN` overrides the default fnm path). Build
+both UIs first; results land in `results/<utc>-<sha7>-<cell>-<ui>-<config>-r<rep>.json`.
+
+```sh
+cd ui-opentui && node scripts/build.mjs && cd ../ui-tui && node scripts/build.mjs && cd ../bench

+### Chaos / pipeline / echo cell notes
+
+- **chaos** (5 scenarios × ink/otui-capped, one JSON each, `summary.chaos`):
+  gateway death is SELF-inflicted (`HERMES_FAKE_DIE_AT=<msg>:<kill|tool-kill>`
+  → SIGKILL at fixture msg N, or at the first `tool.*` event after N) because
+  self-termination is deterministic vs racy external timing; a die-once flag
+  file keeps the auto-heal respawn from dying again. SIGSTOP (gw-stop) is
+  external via `HERMES_FAKE_PIDFILE`. Respawn detection = the respawned
+  gateway REWRITING that pidfile. Both UIs auto-heal (budget 3 respawns/60s):
+  OpenTUI with exponential backoff (`ui-opentui/src/boundary/gateway/liveGateway.ts`
+  `onExit`), Ink immediately (`ui-tui/src/app/useMainApp.ts` `exitHandler`).
+  `transcript_preserved` = after a forced full repaint (resize jiggle), the
+  screen still shows a recent pre-kill turn (`const xN` fixture markers).
+  `summary.result` keeps its usual semantics — for pty-eof the UI *should*
+  die, so read `summary.chaos`, not `summary.result`, for the verdicts.
+- **pipeline**: the ONLY cell that uses tmux — deliberately. The user's real
+  stack runs the TUI inside tmux (verified via /proc environ), so a dedicated
+  `tmux -L hermes-bench-<runId> -f /dev/null` server is the locally measurable
+  terminal-emulator leg. The harness PTY attaches a client (unattached tmux
+  skips most output work; `data_flowing` asserts bytes actually arrived) and
+  samples /proc utime+stime at 1Hz for UI, fake gateway, and the tmux server
+  (`summary.pipeline.cpu_s`). Only that socket's server is killed at the end.
+  Note tmux re-encodes the UI's output for the outer client, so `pty_bytes_total`
+  here is the post-tmux byte count, not the UI's raw output.
+- **frame pacing (M6)**: cpu-paced and pipeline record every PTY chunk
+  timestamp+size; bursts separated by >4ms gaps are frames →
+  `summary.frame_pacing` (fps, interframe p50/p95, bytes/frame p50/p95,
+  coalesced count). Scroll runs record the wheel phase only. There is no
+  env-gated renderer frame counter in ui-opentui to use as ground truth —
+  @opentui/core keeps `renderStats.fps` internally but nothing exports it;
+  wiring it would need a ui-source patch (out of scope here).
+- **echo (M7)**: keystroke chars avoid `u`/`p`/`s`/digits (the OpenTUI status
+  clock repaints `up: Ns` at 1Hz) and matching runs on ANSI-stripped output
+  (raw chunks are full of CSI final letters). The submit leg works because the
+  fake gateway answers `prompt.submit` with a tiny streamed reply carrying the
+  marker token `zqxjv` when `HERMES_FAKE_SUBMIT_RESPONSE=1`.
+
+Configs: `ink` · `otui-capped` (`HERMES_TUI_MAX_MESSAGES=3000`, the default) ·
+`otui-uncapped` (`=100000`). Launch parity with `hermes_cli/main.py`:
+Ink = `node --expose-gc ui-tui/dist/entry.js`, OpenTUI =
+`node --experimental-ffi --no-warnings ui-opentui/dist/main.js`, both with
+`NODE_OPTIONS=--max-old-space-size=<heap>` (8192 on the unconstrained host —
+what the launcher picks outside a container).
+
+## E3 (constrained Docker survival)
+
+`E3-lite` runs the same harness inside a generic `node:26` container (NOT the
+shipped image) with the worktree bind-mounted read-only and `--memory=1g
+--memory-swap=1g`; the whole container (UI + fake gateway + harness) shares the
+limit. See `run-e3.sh` if present, or the report's survival table for the exact
+invocation used.
+
+## What actually ran on 2026-06-11 (E1 host + E3-lite) — deviations from the plan
+
+- **3 reps** for mem3000 (not 5) and **scroll at 2000 msgs** (not 3000): the
+  OpenTUI engine on this tree (sha 197d499, dist built from 50e3471 tree state)
+  **crashes at ≈3000 fixture msgs** — an uncaught `Error: Failed to create
+  SyntaxStyle` (native handle allocation fails; every `TextBufferRenderable`
+  creates one in @opentui/core 0.4.0), masked by a second
+  `Failed to create optimized buffer` crash inside the renderer's
+  uncaughtException handler. Postmortems are in each result's `pty_tail`;
+  RSS at crash ≈880MB — far below the 2GB cap, so it is a handle/pool limit,
+  not memory. This dominates every OpenTUI cell past ~3000 msgs.
+- **OpenTUI headless node-count: not run.** `scripts/mem-bench.tsx` under Node
+  FFI dies on the first fixture turn with `ERR_INVALID_ARG_VALUE … 
+  textBufferViewSetViewport` (the known Bun→Node u32-coordinate class; the
+  production binary carries the ffiSafe clamp, the headless test renderer path
+  does not) and then hangs. The Ink fd-3 sampler ran fine.
+- **Startup real-gateway variant: probed, not run as a cell.** A full run would
+  forge real sessions in the user's `~/.hermes` store. Measured standalone:
+  the real `tui_gateway` (venv python) emits `gateway.ready` in **131ms median**
+  (×10, range 130–138ms) — add that to the fake-gateway startup numbers.
+- **No cgroup OOM kills observed** anywhere (Ink at 10k msgs peaks ~321MB;
+  OpenTUI crashes before reaching the cap), so the cap-hit machinery
+  (memory.events / journal fallback) never fired in anger; E3-lite classified
+  the OpenTUI death correctly as a crash (`oom_kill=0`, exit 7).
+- E2 (shipped Docker image): not run — image build time prohibitive in this
+  session; E3-lite (generic node:26) covers the constrained-memory question.
+- Drain-loop starvation: a handful of OpenTUI burst runs recorded 11–18ms max
+  event-loop lag in the harness (>10ms budget, flagged `drain_ok:false` in
+  those results); all paced/scroll/startup runs stayed under 10ms.
+
+## Accounting + known deviations (by design)
+
+- **"messages" = fixture rows** (`rowsPerTurn` accounting, identical to
+  `ui-opentui/scripts/mem-bench.tsx`), so numbers are comparable with the
+  pre-registered expectations. ~46% of fixture rows are user/system rows.
+- **User/system rows are not streamed**: they are composer-local in both UIs
+  (no wire event exists), so PTY runs mount only the assistant/tool rows —
+  the renderable-heavy part that carries the memory claim. Consequence: the
+  OpenTUI store cap (3000 rows) binds at ≈6.6k fixture-msgs in PTY runs.
+- **Digest gate**: final-screen digest after a resize-forced repaint, ANSI
+  stripped, cut at the composer hint, `up: Ns` normalized (the OpenTUI status
+  bar has a 1Hz uptime clock; the transcript region itself is deterministic).
+- The headless `scripts/mem-bench.tsx` numbers are diagnostic-only and flagged
+  `instrumented`/`diagnostic_only` — never headlined.
+
+## Build/run parity vs an installed hermes (audit, 2026-06-11)
+- Both UIs are built by their own repo build scripts (same artifacts an install produces) and
+  spawned at their real entries: otui `node --experimental-ffi --no-warnings dist/main.js`
+  (identical to production); ink `dist/entry.js` with env mirroring `_launch_tui`
+  (NODE_ENV=production).
+- Two deviations: (1) ink's spawn adds `--expose-gc` — audited: nothing ever calls gc(), the
+  flag is inert; kept for the instrumented sampler runs, harmless in clean runs. (2) both UIs
+  run on the pinned Node 26.3 per protocol ("never compare across Node majors") — installed ink
+  commonly runs Node 20/22, so ink's ABSOLUTE numbers are "ink on Node 26"; the relative
+  comparison is unaffected. An as-installed-Node ink re-run is a worthwhile extra cell.
