Merge branch 'bb/pets' into bb/pets-gen

Carry forward the overlay/waiting-state updates and resolve the gateway merge conflict.
Also tighten the desktop pet-generation flow by cleaning superseded previews,
using the draft's source prompt during hatch, and previewing rows from the
returned sheet taxonomy.

+For most contributors, the best development bootstrap is the same path users
+take: run the standard installer, then work inside the repository it cloned.
+The installer creates the Hermes venv, wires the `hermes` command, stamps the
+install method for `hermes update`, and clones the full git project into
+`$HERMES_HOME/hermes-agent` (usually `~/.hermes/hermes-agent`). That keeps your
+development environment on the same layout the CLI, updater, lazy dependency
+installer, gateway, and docs assume.
+
+```bash
+curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
+cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
+
+# Add dev/test extras on top of the standard install.
+uv pip install -e ".[all,dev]"
+
+# Optional: browser tools / docs site dependencies.
+npm install
+```
+
+After that, create branches and run tests from that checkout:
+
+```bash
+git checkout -b fix/description
+scripts/run_tests.sh
+```
+
+### Manual clone fallback
+
+Use this only if you intentionally do not want Hermes' managed install layout
+(for example, a throwaway clone inside a container or CI job). If you install
+this way, make sure you run the `hermes` entrypoint from this venv; running the
+system `python3 -m hermes_cli.main` can pick up unrelated system Python
+packages.

+"""Petdex pet engine — shared core for the CLI, TUI, and desktop surfaces.
+
+Petdex (https://github.com/crafter-station/petdex) is a public gallery of
+animated sprite "pets" for coding agents.  Each pet is a ``pet.json`` plus a
+``spritesheet.{webp,png}`` of 192×208 px cells. Current Codex/petdex sheets use
+an 8-column × 9-row atlas; older Hermes/petdex sheets used an 8-row atlas.
+Hermes infers the row taxonomy from the sheet and maps agent activity onto
+idle/run/review/failed/wave/jump.
+
+This package is the **single source of truth** for the feature so the base
+CLI (Python) and TUI (Ink, via ``tui_gateway``) never duplicate the hard
+parts:
+
+- :mod:`agent.pet.constants` — frame geometry + the :class:`PetState` enum.
+- :mod:`agent.pet.state`     — map agent activity → a :class:`PetState`.
+- :mod:`agent.pet.manifest`  — fetch the public petdex manifest.
+- :mod:`agent.pet.store`     — install / list / resolve pets on disk
+                               (profile-aware via ``get_hermes_home()``).
+- :mod:`agent.pet.render`    — decode a spritesheet and encode frames for a
+                               terminal (kitty / iTerm2 / sixel graphics
+                               protocols, with a Unicode half-block
+                               fallback).
+
+Rendering in the Electron desktop is necessarily TypeScript (canvas), but it
+reuses the same on-disk store and the same state semantics.
+
+The whole feature is a *display* concern: it adds no model tool, mutates no
+system prompt or toolset, and therefore has zero effect on prompt caching.
