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).

+# Doc Review: add-state-loop-lock
+
+Reviewed docs touched by or referring to the fix.
+
+## Files reviewed
+
+- `CHANGELOG.md` — added `### Added — .state.loop file lock (task add-state-loop-lock)` at the top of `[unreleased]` covering R1-R7 + D-L1 through D-L6, the env-var mechanism, callsites wrapped in both scripts, the test plan, the adversarial findings, backwards-compat, stdlib-only constraint, and 447-passing count.
+- `AGENTS.md` — added a `.state.lock` (v1.1) bullet under State Enforcement — Loops (v1) summarizing the lock shape, granularity, blocking-acquire behavior, env-var mechanism, and pointer to the technical doc.
+- `README.md` — extended the Loop Engineering runtime paragraph with a single sentence pointing at `.state.lock` serialization with a `design/loops/technical.md §7` pointer.
+- `design/loops/technical.md` §7 — added a new "Lock serialization" subsection covering the lock shape, callsites in both scripts, the env-bypass mechanism (D-L6), the re-entry forbidding audit, and the harness-contractor-loop-control implication.
+- `contracts/harness-integration.md` — no edits. The A4 follow-up "forbid loop-control commands inside a tick" is deferred to a small docs-only follow-up (not a blocker); listed in the design doc. Did NOT modify the harness integration contract in this task to avoid scope-creep.
+- `prompts/loop-*.md` — no edits (phase prompts are content; no locking references there).
+- `scripts/install.sh` / `scripts/update.sh` / `scripts/upgrade.sh` — no edits (don't touch the lock).
+
+## Cross-references checked
+
+- `rg "_loop_lock|\.state\.lock|AUTOMATON_NO_LOOP_LOCK" design/ templates/ scripts/ contracts/ README.md AGENTS.md prompts/` — all hits intentional.
+- `rg "fcntl|msvcrt|flock" design/loops/technical.md AGENTS.md README.md` — only intentional references in the new docs.
+- The `add-loop-runner/` v1 CHANGELOG entry still says "the runner writes `.state.loop` atomically via `_write_state_loop` (tmp file then replace)" — this remains accurate (the atomic write is still in place; the lock adds a coarse mutex on top — defense-in-depth per D-L5).

+PASS — proceed to referee.
