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).

+
+### `.rules.md`
+Added "Changelog" section:
+- When a task reaches Resolution (VERDICT.md written), append an entry to CHANGELOG.md

+# SPEC: Changelog and Release Notes Process
+
+## Overview
+
+There's no changelog or release note process. Completed tasks produce a VERDICT.md but there's no aggregate record of what changed. This makes it hard to generate release notes or see the project's history at a glance.
+
+## Changes
+
+### 1. `CHANGELOG.md` at `~/.automaton/`
+
+Root-level changelog file with entries appended on task completion:
+
+```markdown
+# Changelog
+
+## [unreleased]
+
+### Added
+- description (#task-name)
+
+### Fixed
+- description (#task-name)
+```
+
+### 2. Update `.rules.md`
+
+Add a rule: "When a task reaches Resolution (VERDICT.md written), append an entry to CHANGELOG.md."
+
+## Acceptance Criteria
+
+- [ ] `~/.automaton/CHANGELOG.md` exists with [unreleased] header
+- [ ] `.rules.md` mentions changelog updates as part of task completion
+- [ ] Format is clean enough to use as release notes source
