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).

+# Adversarial Bug Report: add-outputs-retention
+
+Probed `_get_retention` and `_gc_outputs` with non-contract inputs.
+
+## A1 — `retention` as float
+
+`_get_retention({"outputs": {"retention": 3.14}})` → `int(3.14)` = 3. Not garbage but truncating. Acceptable (float is a numeric type; int() rounds toward zero). Not a regression.
+
+## A2 — `retention` as bool
+
+`_get_retention({"outputs": {"retention": True}})` → `int(True)` = 1. A user who sets `retention: true` intending "unlimited" gets 1 (wrong — they wanted 0). But `bool` is technically a subclass of `int` in Python; `int(True)` = 1 is documented behavior. Acceptable edge case — the user would need to write JSON `true`, which `json.loads` reads as `True`. Not blocking; `int(True)` = 1 is a narrow retention but valid.
+
+## A3 — `retention` string "inf" falls back to 20
+
+`_get_retention({"outputs": {"retention": "inf"}})` → `int("inf")` raises ValueError → caught → 20 with WARNING. Correct per SPEC D-O4.
+
+## A4 — GC handles large gaps in tick indices
+
+Files `tick1-*.json` and `tick100-*.json` with nothing in between: `max_seen=100`, `retention=20`, `cutoff=100-20+1=81`. Deletes tick1- but keeps tick100-. Correct — the gap is intentional (maybe intermittent ticks). Not a bug.
+
+## A5 — Non-tick files `tick-nope.md` preserved
+
+Hyphen-no-number prefix `tick-nope.md` doesn't match `^tick(\d+)-`. Preserved. Correct per D-O6.
+
+## A6 — Empty outputs dir
+
+`_gc_outputs` on dir with 0 files or missing dir returns cleanly. No crash. Confirmed.
+
+## No BLOCKERS
+
+All adversarial cases produce deterministic documented results. Proceed to doc_review.
