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: add-self-improvement-loop
+
+## Summary
+
+Wired the self-improvement loop into `install.sh` (default-on for fresh installs) and `update.sh` (idempotent bootstrap for existing users). Both use `status.py --create-loop self-improvement --from-template self-improvement` and `--install-schedule self-improvement --interval 3600` with `|| true` to ensure the framework continues to work even if loop creation fails.
+
+## Changes
+
+### R1 -- `scripts/install.sh`
+
+Added after guard registration (inside the `else` block, before `fi`):
+- `--create-loop self-improvement --from-template self-improvement --project "$FRAMEWORK_DIR"` with `|| true`
+- `--install-schedule self-improvement --interval 3600 --project "$FRAMEWORK_DIR"` with `|| true`
+- User-facing message about the self-improvement loop and how to disable it with `--pause-loop`
+
+### R2 -- `scripts/update.sh`
+
+Added after guard registration:
+- Idempotent check: `if [ ! -d "$FRAMEWORK_DIR/loops/self-improvement" ]`
+- Same `--create-loop` and `--install-schedule` commands with `|| true`
+- Info message when the loop is created
+
+### R3 -- `tests/test_self_improvement_loop.py`
+
+16 tests across 4 classes:
+- `TestInstallShWiring` (5 tests): verify install.sh contains create-loop, install-schedule, opt-out message, framework project, and `|| true`
+- `TestUpdateShWiring` (4 tests): verify update.sh contains create-loop, idempotent check, install-schedule, and `|| true`
+- `TestSelfImprovementTemplate` (5 tests): verify template fields (audit work source, brakes, worktree, file scope, role prompts)
+- `TestCreateLoopFromTemplate` (2 tests): simulate `--create-loop self-improvement --from-template self-improvement` and verify directory structure; verify duplicate creation is refused
+
+### R4 -- Documentation
+
+- `CHANGELOG.md`: task 7 entry under `[unreleased]`
+- `README.md`: note that self-improvement loop is default-on at install
+- `design/loops/technical.md` section 9: note that install.sh creates it default-on
+
+## Verification
+
+- `bash -n scripts/install.sh scripts/update.sh` -- OK
+- `python3 -m pytest tests/test_self_improvement_loop.py -v` -- 16 passed
+- `python3 -m pytest tests/ -q` -- 409 passed (393 + 16 new)
