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.md — Fix Guard Plugin Derailment
+
+## Changes Made
+- `plugins/automaton-guard/plugin.ts:60-65`: Replaced `client.chat()` injection with `throw new Error()`
+
+## How It Works
+- When an edit is blocked, the guard now throws an error instead of injecting synthetic user messages
+- This prevents derailing the agent's context mid-operation
+- The harness handles the error cleanly without contaminating message history
+- The error message still includes actionable instructions for creating/transitioning tasks

+# Fix Guard Plugin Derailment
+
+## Problem
+The automaton-guard plugin (`plugins/automaton-guard/plugin.ts:61-64`) calls `client.chat()` with `role: "user"` when an edit is blocked. This injects synthetic user messages that can derail agent context mid-operation.
+
+## Fix
+Replace the `client.chat()` call with returning an error through the output mechanism, using `throw new Error()` or equivalent so the harness handles the rejection cleanly without contaminating the agent's message history.
+
+## Verification
+- Guard plugin rejects blocked edits without injecting user messages
+- Agent context is not contaminated
