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).

+# VERDICT: add-blast-radius-scheduler
+
+**Status: PASS**
+
+Task delivers per-loop git worktree creation in the runner, closing the last gap in the blast-radius enforcement chain. With this task, the runner ensures a worktree exists before spawning any role, the drift gate checks it, and `--can-edit --loop-worktree` scopes file edits to it.

+
+## Blast-radius enforcement chain -- complete
+
+1. **Worktree creation** (this task): runner creates `<loop>/worktree` on branch `loop/<name>`.
+2. **Drift detection** (task 2): `--check-gate` runs `git diff --name-only main...HEAD` restricted to `file_scope`.
+3. **File scope enforcement** (task 2): `--can-edit --loop [--loop-worktree]` checks paths against `blast_radius.file_scope`.
+4. **Graceful fallback** (this task): non-git projects fall back to project root with WARNING; drift gate skips when `worktree_path` is null.
+
+## Agnosticism preserved
+
+- **Git-agnostic**: falls back gracefully when git is unavailable. Loops on non-git projects work (edits go to primary checkout).
+- **Platform-agnostic**: `pathlib.Path` for all path construction. Git handles OS-specific path normalization.
+- **Model-agnostic**: no model inspection. Worktree creation is infrastructure, not model behavior.
+
+## Hardening items deferred
+
+1. Worktree GC / pruning (BACKLOG `worktree-gc`) -> v1.1.
+2. `--no-worktree` CLI flag for `--create-loop` -> v1.1 (convenience sugar).
+3. `blast_radius.base_branch` parameterization -> v1.1.
+4. fcntl lock on worktree creation (TOCTOU A4) -> v1.1 (same item as `add-status-brakes` A6).
+
+## Resolution
+
+**PASS -- proceed to `complete`.** Task 5 completes the blast-radius enforcement chain. The runner now creates worktrees, the drift gate checks them, and `--can-edit` scopes file edits. Remaining tasks: 6 (templates-onboarding), 7 (self-improvement-loop), 8 (install-update-flow), 9 (move-completed-tasks).
