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: Autopilot Gate Integration
+
+## Changes Made
+
+### 1. Gate-between-phases in autopilot
+The orchestrator prompt (`prompts/orchestrate.md`) now defines an explicit gate-check loop:
+1. Read `.state` → confirm current phase
+2. Run `status.py --validate-folder` → check for out-of-order artifacts
+3. If violations found → STOP and report
+4. Load phase prompt → confirm ALLOWED/FORBIDDEN boundaries
+5. Execute phase → produce required artifact
+6. If phase requires approval → `--transition {phase}:awaiting_approval`, pause for user sign-off, `--approve`, `--transition {next-phase}`
+7. If phase does NOT require approval → `--transition {next-phase}`
+
+### 2. Resumption from `.state`
+- The orchestrator reads `.state` for each task, no artifact re-derivation needed
+- Approval sub-states are preserved across sessions
+
+### 3. Persona switching
+- Orchestrator loads the prompt for the current phase based on `.state`
+- FORBIDDEN sections in phase prompts constrain what the orchestrator can do
+- Orchestrator must NOT override phase-level FORBIDDEN rules
+
+### 4. Approval gates in autopilot
+- Research, decomposition, design, and test_design phases ALWAYS pause for user approval in autopilot
+- The pause is enforced by `status.py --transition` refusing past `:awaiting_approval`
+- After user says "APPROVED", `status.py --approve` is called, then transition proceeds
+
+### 5. Session break recovery
+- `.state` file records the last completed phase (including approval sub-states)
+- Next session reads `.state` and resumes exactly where it left off
+- No phase progress is lost on session break
+
+### 6. Manual mode coexistence
+- Orchestrator reads `.state` and reports current phase
+- User triggers phases manually, orchestrator calls `status.py --transition` and `status.py --approve`
+
+### 7. Periodic audit
+- Orchestrator calls `status.py --audit` at session start and after task completion
+- Catches violations that might slip through individual phase gates
+
+## Files Modified
+- `prompts/orchestrate.md` (rewritten, 143 lines with gate-check loop)
+- `prompts/workflow.md` (referenced from orchestrate.md)
