docs: two-week gap sweep — platforms, CLI, config, TUI, hooks, providers (#17727)

Covers ~60 merged PRs from Apr 15–29 that shipped user-visible behavior
without docs coverage. No functional code changes; docs + static manifest
regeneration only.

Highlights:

Stale / incorrect:
- configuration.md: auxiliary auto-routing line was wrong since #11900;
  now correctly states auto routes to the main model, with a note on the
  cost trade-off and per-task override pattern.
- integrations/providers.md + configuration.md compression intro:
  removed stale 'Gemini Flash via OpenRouter' claim.
- website/static/api/model-catalog.json: rebuilt from hermes_cli/models.py
  so the live manifest picks up tencent/hy3-preview (and remains in sync
  for future model-catalog PRs).

 | `/details` | Toggle verbose tool-call details (global or per-section) |

 Every other slash command (including installed skills, quick commands, and personality toggles) works identically to the classic CLI. See [Slash Commands Reference](../reference/slash-commands.md).
 
+## LaTeX math rendering
+
+The TUI's markdown pipeline renders LaTeX math inline: `$E = mc^2$` and `$$\frac{a}{b}$$` render as Unicode-formatted math instead of the raw TeX source. Works for inline and block math; unsupported syntax falls back to showing the literal TeX wrapped in a code span so it remains copyable.
+
+This is always-on — nothing to configure. Classic CLI keeps the raw TeX.
+
+## Light-terminal detection
+
+The TUI auto-detects light terminals and swaps to the light theme accordingly. Detection works in three layers:
+
+1. `HERMES_TUI_THEME` env var — highest priority. Values: `light`, `dark`, or a raw 6-char background hex (e.g. `ffffff`, `1a1a2e`).
+2. `COLORFGBG` env var — the classic "what's my background color?" hint used by xterm-derived terminals.
+3. Terminal background probe via OSC 11 — works on modern terminals (Ghostty, Warp, iTerm2, WezTerm, Kitty) that don't set `COLORFGBG`.
+
+If you want the light theme permanently regardless of terminal:
+
+```bash
+export HERMES_TUI_THEME=light
+```
+
+## Busy indicator styles
+
+The status-bar FaceTicker is pluggable — the default rotates Hermes' kawaii face palette every 2.5 seconds during agent work. Pick a different style (or `none` for a minimal dot) via config:
+
+```yaml
+display:
+  busy_indicator:
+    style: kawaii     # kawaii | minimal | dots | wings | none
+```
+
+Styles ship with matched glyph widths so the rest of the status bar doesn't jitter on rotation.
+
+## Auto-resume
+
+By default, `hermes --tui` starts a fresh session each launch. To re-attach to the most recent TUI session automatically (useful when your terminal or SSH connection drops unexpectedly), opt in:
+
+```bash
+export HERMES_TUI_RESUME=1          # most-recent TUI session
+# or:
+export HERMES_TUI_RESUME=<session-id>   # specific session
+```
+
+Unset the variable or pass `--resume <id>` explicitly to override on a per-launch basis.

 The per-skin status-bar colors and thresholds are shared with the classic CLI — see [Skins](features/skins.md) for customization.
 
+The status line also shows:
+
+- **Working directory with git branch** — `~/projects/hermes-agent (docs/two-week-gap-sweep)`. The branch suffix updates when you `git checkout` in a side terminal (mtime-cached) so the TUI reflects your actual active branch, not whatever it was at launch.
+- **Per-prompt elapsed time** — `⏱ 12s/3m 45s` while the turn is running (live), frozen to `⏲ 32s / 3m 45s` after the turn completes. First number is time since last user message; second is total session duration. Resets on every new prompt.
+
 ## Configuration
 
 The TUI respects all standard Hermes config: `~/.hermes/config.yaml`, profiles, personalities, skins, quick commands, credential pools, memory providers, tool/skill enablement. No TUI-specific config file exists.
