chore: post-Phase-1 cleanup — gitignore, packaging, backlog

- .gitignore: add *.egg-info/ so editable installs don't show in git status.
- pyproject.toml: add [build-system] and [tool.setuptools.packages.find]
  scoped to chat*, fixing pip install -e . which was failing on data/
  auto-discovery.
- CLAUDE.md: add Phase 1.5 cleanup backlog section under Phase 1 status,
  capturing the small follow-ups surfaced in implementer reviews
  (open_db refactor, regenerate SSE broadcast, you-activity purge,
  drawer edits for deferred fields, NICE trim order).

 - **8-pin auto-cap eviction** is FIFO over the auto-pinned set only. Manual pins survive the eviction; this is by design (manual intent > auto-pin signal).
 - **Regenerate (T29) does not broadcast `turn_html` over SSE** — the page must refresh to show the regenerated turn. Acceptable for v1 single-tab usage; Phase 1.5 should wire the SSE event.
 - **First-run middleware** fires only on bare `/` and `/chats`. Sub-paths like `/chats/<id>` and `/chats/<id>/drawer` pass through (correct: HTMX partials should not page-redirect, and a deep-link to a missing chat should 404, not redirect mid-setup).

+- **`open_db` refactor.** `chat/web/bots.py:get_conn()` duplicates the context-manager body to add `check_same_thread=False`. Extend `open_db(path, *, check_same_thread=True)` and have `get_conn` call it directly — eliminates the duplicated PRAGMA setup and ensures any future PRAGMA tweak only happens in one place.
+- **Regenerate broadcasts `turn_html` over SSE.** Currently a refresh is needed (see T29 limitation above). Mirror the broadcast logic from `chat/web/turns.py:post_turn` after the new `assistant_turn` lands.
+- **`bot_reset` purges orphaned "you" activity rows** (see limitation above). Either delete `activity` rows by chat-membership or accept the noise indefinitely; the projection-layer fix is one extra `DELETE FROM activity WHERE entity_id='you' AND container_id IN (SELECT id FROM containers WHERE chat_id IN (...))` clause inside `_apply_bot_reset`.
+- **Drawer edits for the deferred v1 fields**: edge_trust slider, edge_summary textarea, memory pov_summary textarea, knowledge_facts add/remove. The `manual_edit` projector already supports `edge_trust` / `edge_summary` / `memory_pov_summary` target_kinds — only the routes are missing. Knowledge_facts needs a new dispatch branch.
+- **NICE trim order in prompt assembly** drops previous-scene first instead of last (T18 review). Greedy-cuts heuristic vs spec listing order; revisit if v1 play surfaces a real regression.
