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).

+# Implementation: Status Script
+
+## Changes Made
+
+### 1. Core script: `scripts/status.py` (980 lines)
+Full implementation of all commands specified in the SPEC:
+
+- `--task {name}` — Shows phase, allowed/forbidden actions, next artifact, next phase, approval status
+- `--list` — Lists all tasks with phase and next step
+- `--create-task {name}` — Creates task folder with `.state`=new, validates kebab-case, refuses duplicates
+- `--transition {phase}` — Validates and writes `.state` transitions, refuses illegal transitions, refuses past `:awaiting_approval` without `--approve`, validates required artifacts and forbidden artifacts
+- `--approve` — Transitions `:awaiting_approval` → `:approved`, records in `.state.approvals`, refuses if not in awaiting_approval sub-state
+- `--validate-folder` — Checks for out-of-order artifacts, flags manually created tasks
+- `--audit` — Four categories: out-of-order artifacts, state-artifact inconsistency, unauthorized git modifications, manually created tasks
+- `--claim / --release` — Multi-agent task claiming with `.state.lock` files, timeout, overclaiming
+- `--next-available / --available` — Work discovery for multi-agent, filters by agent role
+- `--can-edit` — Returns ALLOWED/DENIED based on current phase
+- `--scope-check` — Returns IN_SCOPE/OUT_OF_SCOPE for file paths
+- `--same-session` — Heuristic session check
+
+### 2. Approval sub-states
+- Phases with approval: research, decomposition, design, test_design
+- Sub-states: `{phase}:awaiting_approval` and `{phase}:approved`
+- `--transition` refuses past `:awaiting_approval` without `--approve`
+- `--approve` records timestamp and approver in `.state.approvals`
+
+### 3. Forbidden artifacts per phase
+- Full mapping from SPEC implemented in FORBIDDEN_ARTIFACTS dict
+- `--validate-folder` checks and reports violations
+- `--transition` refuses if forbidden artifacts exist
+
+### 4. Multi-agent support
+- Agent Configuration parsed from `.agent.md`
+- `.state.lock` files with agent ID, phase, claimed timestamp, expiry
+- Configurable lock timeout (default 30 min)
+- `--claim` validates agent is configured for the phase
+- `--next-available` returns highest-priority unclaimed task matching agent phases
+
+### 5. Tests: `tests/test_status.py` (25 tests)
+- Create task (valid, invalid names, duplicates)
+- State transitions (legal, illegal, approval gates)
+- Approval gates (approve, refuse wrong phase, record log)
+- Folder validation (valid, no state file, out-of-order artifacts)
+- Artifact validation (missing required, forbidden)
+- Show task (phase display, allowed/forbidden)
+- List tasks
+- Tool hooks (can-edit, scope-check)
+- Audit (manual tasks, clean tasks)
+
+## Files Created
+- `scripts/status.py` (980 lines)
+- `tests/test_status.py` (25 test cases)
+
+## Test Results
+- 183 tests passing (including all 25 new status.py tests)
+- Python compilation clean
