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).

+# Code Review: add-outputs-retention
+
+## SPEC coverage
+
+| Requirement | Status |
+|-------------|--------|
+| R1 — `_get_retention` helper from `outputs.retention` | ✓ |
+| R2 — GC executes on every tick (post-write) | ✓ step 10.5 inside `_loop_lock` |
+| R3 — Retention = 0 means no GC | ✓ `if retention <= 0: return` |
+| R4 — GC failure doesn't crash tick | ✓ OSError caught → WARNING log + swallow |
+| R5 — No new pip deps | ✓ stdlib only |
+
+## Cross-script impact
+
+- `scripts/loop-runner.py`: pure addition; no existing function changed.
+- `templates/loops/self-improvement/loop.json`: new `outputs.retention: 20` field.
+- `scripts/status.py`: no changes needed (create-loop template provides the default; runner reads, not status.py).
+
+## Off-by-one fix
+
+GC formula was `cutoff = max_seen - retention` (kept retention+1 groups). Found during test execution when `test_gc_keeps_recent_deletes_old` showed 21 remaining instead of 20. Fixed to `cutoff = max_seen - retention + 1`. Good test coverage.
+
+## Verdict
+
+PASS — proceed to bug_find.
