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).

+# Harden Enforcement Layers Implementation
+
+## Summary
+Added pre-push hook, install-hooks.sh, plugin auto-registration, and prompt pre-edit checks to harden all enforcement layers.
+
+## Changes
+
+### New Files
+- `scripts/git-hooks/pre-push` — Blocks pushes when no task is in edit-allowed phase; catches `--no-verify` bypasses
+- `scripts/install-hooks.sh` — Installs pre-commit + pre-push hooks into a project
+- `scripts/register-guards.sh` — Auto-detects opencode/pi dev harnesses and registers guard plugins
+
+### Modified Files
+- `contracts/harness-integration.md` — Updated to 4-layer enforcement model (added pre-push)
+- `prompts/doc_review.md` — Added pre-edit check section (MANDATORY)
+- `prompts/implement.md` — Added pre-edit check section (MANDATORY)
+- `prompts/orchestrate.md` — Added task creation section with clock-touch instructions
+- `scripts/install.sh` — Calls register-guards.sh post-install; updated hook installation docs
+- `scripts/update.sh` — Calls register-guards.sh; auto-installs hooks in current project
+- `scripts/upgrade.sh` — Installs both pre-commit and pre-push hooks (previously pre-commit only)
+- `system-prompt.md` — Added hook verification step and task-required-before-edits rule
+- `scripts/git-hooks/pre-commit` — Cleaned up error messages (removed bypass/upgrade instructions)
