Restore archived tasks, fix dashboard scroll-reset, bind ornith, add Playwright smoke test

- **Restore 82 completed tasks** from tasks/complete/ back to tasks/ top
  level (all <7 days old per the cleanup policy; premature bulk archive
  was fixed).
- **Dashboard: fix scroll-reset on auto-refresh** — renderBoard rebuilds
  the board via innerHTML every 2s, destroying each column-body's
  scrollTop. Now snapshots column-body scrollTop + board.scrollLeft +
  view.scrollTop before rebuild and restores after (matched by
  PHASE_GROUPS index).
- **Dashboard UI additions** (pre-existing unstaged work): approval
  section cards, transition buttons, inline artifact editor (textarea for
  writing missing SPEC/VERDICT/etc from the detail modal).
- **Bind ornith as Implement model** — config.md: Model explicit to
  omlx/Ornith-1.0-35B-4bit-mlx, context window 32768. Interactive
  autopilot already used ornith via opencode default; now explicit.
- **Fix cleanup stub** — automaton-cleanup.sh had a stale --project arg
  pointing at a pytest temp dir (test isolation leak). Rewired to point
  at ~/.automaton.
- **Fix plist-isolation test** — test asserted host plist doesn't exist,
  but a real install creates it. Now snapshots mtime before run, asserts
  unchanged after (only a write during the test counts as bleed).
- **New Playwright smoke test** (tests/test_dashboard_ui.py) — 2 tests:
  board renders tasks, column scroll survives auto-refresh tick.
  Verified the test fails without the scroll fix (scrollTop resets to 0).
  Skipped via importorskip when playwright is absent (main CI stays
  green).
- **Clarify SI loop scope in README** — new-project onboarding section
  documents the framework-scoped self-improvement loop and options
  (leave/pause/create project loop).
- **CHANGELOG** documents all changes including the known model-divergence
  gap (mde tasks marked complete but per-role model binding was never
  implemented).

+# Implementation: Hook Installation in Onboarding and Upgrade
+
+## Changes
+
+### 1. prompts/onboarding.md — Step 2c: Pre-Commit Hook Installation
+- Added Step 2c between VRAM config and Output sections
+- Checks for `.git/hooks/` directory
+- Creates symlink from `.git/hooks/pre-commit` to `~/.automaton/scripts/git-hooks/pre-commit`
+- Warns if existing hook is not our symlink
+- Verifies hook works with `status.py --can-edit`
+
+### 2. scripts/upgrade.sh — Hook installation during upgrade
+- Added after the "Upgrade Complete" message
+- Detects `.git/hooks/` directory
+- If hook doesn't exist: creates symlink
+- If hook is already our symlink: reports "already linked"
+- If hook exists but is not our symlink: warns user, prints manual install command
+- If no `.git/hooks/`: prints note with manual install command
+
+### 3. scripts/install.sh — Post-install next steps
+- Replaced single "Next step" with numbered list
+- Added hook installation as step 2
+- Added explanation of what the hook does
+
+## Tests
+- All 200 tests pass
+- Shell syntax checks pass for install.sh and upgrade.sh
