Lap Tran bc7daf8590 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: Multi-Agent Support
## Changes Made
### 1. Agent Configuration in `.agent.md`
Multi-agent mode is activated by adding an `## Agent Configuration` section to `.agent.md`:
```markdown
## Agent Configuration
Mode: multi-agent
Agents:
- id: researcher
phases: [research, decomposition, design, test_design]
- id: implementer
phases: [implement]
- id: orchestrator
phases: [new, complete, human_intervention]
role: coordinator
Lock timeout: 30m
```
When this section is absent or `Mode: single-agent` (default), all multi-agent commands are no-ops.
### 2. Task claiming: `--claim` and `--release`
- `status.py --claim --task {name} --agent {id}` creates `.state.lock` with agent ID, phase, claimed timestamp, and expiry
- Atomic write (`.state.lock.tmp` → `.state.lock`)
- Refuses if already claimed and not expired
- Overclaims expired locks with warning
- Validates agent is configured for the task's current phase
- Default lock timeout: 30 minutes, configurable in `.agent.md`
### 3. Work discovery: `--next-available` and `--available`
- `--next-available --agent {id}` returns the highest-priority unclaimed task matching the agent's allowed phases
- Priority: tasks closest to completion first (referee > doc_review > ... > research > new)
- `--available --agent {id}` lists all matching tasks
- In single-agent mode, both return a message directing to `--list`
### 4. Single-agent zero-overhead guarantee
- When no Agent Configuration exists, `--claim`, `--release`, `--next-available`, `--available` are no-ops or return guidance messages
- No `.state.lock` files are created in single-agent mode
- No performance overhead, no behavioral change from v1
### 5. Coordinator role
- Agent with `role: coordinator` can:
- Claim tasks on behalf of other agents (`--claim --agent {target} --as-coordinator`)
- Force-release claims (`--release --as-coordinator`)
- Force-transition (`--transition {phase} --force`)
### 6. Lock expiry and conflict resolution
- Locks expire after configurable timeout (default 30 min)
- Any agent can overclaim expired locks
- Atomic lock writes prevent race conditions
- Locks auto-release on `complete` and `human_intervention` transitions
### 7. Role binding in phase prompts
- When multi-agent mode is active and `--agent` is provided, `status.py --task` includes agent-specific ALLOWED/FORBIDDEN sections
- Phase prompts include `## Agent Role` section when agent is role-bound
- `TASK_HANDOFF` signal defined for when agent can't perform a required phase
## Files Modified
- `scripts/status.py` (multi-agent commands implemented)
- `tests/test_status.py` (existing tests cover single-agent; multi-agent requires Agent Configuration to test)
## Notes
- Multi-agent is opt-in: zero config changes needed for single-agent usage
- The phase prompt `## Agent Role` section is documented in the `multi-agent-support/SPEC.md` but will be dynamically generated by `status.py --task` output when multi-agent is active
- Dashboard integration for multi-agent status display is future work
