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: fix-stale-task-mtime-proxy
+
+## Reviewed Files
+- `scripts/status.py` (`_get_edit_timestamp()`, `_touch_lastedit()`, `cmd_can_edit()`, `cmd_same_session()`, `cmd_touch()`, `NON_ARTIFACT_FILES`)
+
+## Changes
+1. Added `.state.lastedit` file as the stale-task timer source
+2. `_touch_lastedit()` called on ALLOWED `--can-edit` responses
+3. `_get_edit_timestamp()` reads `.state.lastedit` with fallback to `.state` mtime
+4. Added staleness check to single-task `--can-edit --task` path
+5. `--touch` now touches `.state.lastedit` instead of `.state`
+
+## Analysis
+- **Correctness**: Using `.state.lastedit` (touched on actual edit activity) is a better proxy for staleness than `.state` mtime (which only reflects phase transitions)
+- **Backward compatibility**: Falls back to `.state` mtime when `.state.lastedit` doesn't exist
+- **Non-artifact**: `.state.lastedit` correctly added to `NON_ARTIFACT_FILES` to avoid being treated as a phase artifact
+- **Single-task path**: Adding staleness check to `--can-edit --task` makes enforcement consistent across both code paths
+- **`--touch` command**: Updated to touch `.state.lastedit` — consistent with the new activity tracking model
+
+## Verdict: PASS
+
+The fix is well-structured, maintains backward compatibility, and correctly addresses the mtime proxy issue. Tests cover creation, staleness detection, and fallback behavior.
