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: fix-vram-model-prefix-match
+
+## Bug
+`_lookup_model_context()` in `vram_detect.py` used raw `startswith()` for model name matching, causing false positives like `phi-4` matching `phi-40` or `phi-4-mini-instruct` (a different model with different context window).
+
+## Fix
+Replaced the raw `startswith()` with a three-tier matching strategy:
+1. **Exact match** — `name_lower == key_lower`
+2. **Ollama parameter tag** — `name_lower.startswith(key_lower + ":")` (e.g. `deepseek-r1:7b` matches `deepseek-r1`)
+3. **Known instruction-tuning suffix** — `name_lower.startswith(key_lower + "-")` only if the next segment is in `_KNOWN_MODEL_SUFFIXES = {"instruct", "chat", "it", "fp16", "f16", "bf16"}` (e.g. `llama-3.1-8b-instruct` matches `llama-3.1-8b`)
+
+Keys are sorted by length descending so the most specific match wins first.
+
+This prevents false matches:
+- `phi-4-mini-instruct` → `mini` not in known suffixes → no match ✓
+- `gpt-4o-foo-unknown` → `foo` not in known suffixes → no match ✓
+- `phi-40` → no `:` or known-suffix separator → no match ✓
+
+## Files Changed
+- `scripts/vram_detect.py`: Added `_KNOWN_MODEL_SUFFIXES` set, rewrote `_lookup_model_context()` with three-tier matching
+
+## Tests
+- `test_lookup_model_context_no_false_prefix_match`: Asserts `phi-4-mini-instruct` and `gpt-4o-foo-unknown` return 0
+- Existing `test_lookup_model_context_prefix_match` still passes (deepseek-r1:7b and llama-3.1-8b-instruct)
