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).

+# Bug Report: State File Enforcement
+
+## Methodology
+Reviewed status.py implementation of .state file format, approval sub-states, atomic writes, forbidden artifacts per phase, task creation gate, and state transition rules.
+
+## Acceptance Criteria
+| # | Criterion | Result |
+|---|-----------|--------|
+| 1 | `.state` file format with approval sub-states | ✅ |
+| 2 | Atomic write mechanism (tmp+rename) | ✅ |
+| 3 | Forbidden artifacts per phase enforced | ✅ |
+| 4 | `--validate-folder` flags folders without `.state` | ✅ |
+| 5 | `--audit` flags manually created task folders | ✅ |
+| 6 | Task creation gate (`--create-task`) | ✅ |
+| 7 | Approval sub-states for research/design/decompose/test_design | ✅ |
+| 8 | `:awaiting_approval` → `:approved` only via `--approve` | ✅ |
+| 9 | `.state` excluded from artifact heuristics | ✅ |
+
+## Findings
+1. **Minor**: The `.gitignore` pattern for `.state` was not explicitly added to a project-level gitignore — it's documented as metadata but not enforced in version control.
+
+## Verdict: PASS
