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-blast-radius-scheduler
+
+Reviewed doc impact for task `add-blast-radius-scheduler`.
+
+## Doc edits in this task
+
+### 1. `design/loops/technical.md` section 7 step 4
+Updated to document the runner's worktree creation behavior, including branch-exists retry and non-git fallback. No "deferred" language remains. PASS
+
+### 2. `CHANGELOG.md`
+New `[unreleased]` entry for blast-radius scheduler. PASS
+
+### 3. `AGENTS.md`
+No new CLI surface. The runner's worktree creation is internal behavior, not a user-facing command. No change needed.
+
+### 4. `README.md`
+The loop engineering section already mentions per-loop worktrees (D2). No change needed.
+
+### 5. `design/loops/functional.md`
+Already documents `--no-worktree` as the opt-out mechanism (via `blast_radius.use_worktree: false`). No change needed.
+
+### 6. `templates/loops/ci-triage/loop.json`
+Already has `"use_worktree": true` in `blast_radius`. No change needed.
+
+### 7. `prompts/`
+No prompt changes in this task. No change.
+
+## Code-doc consistency check
+
+- `technical.md` section 7 step 4: worktree creation flow matches `_ensure_worktree` implementation. PASS
+- `functional.md` section on `--no-worktree`: matches `use_worktree: false` behavior. PASS
+- `ci-triage/loop.json` `blast_radius.use_worktree`: matches the default-true behavior when field is missing. PASS
+
+## Summary
+
+Doc edits in this task:
+- `design/loops/technical.md` section 7 step 4 updated.
+- `CHANGELOG.md` new entry.
+
+No code-doc mismatches. READY for referee.
