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).

+# SPEC: add-self-improvement-loop
+
+## Context
+
+Task 6 created the self-improvement loop template at `templates/loops/self-improvement/loop.json`. This task wires it into `install.sh` and `update.sh` so the loop is default-on at install time (D21). Existing users who run `update.sh` get the loop bootstrapped idempotently.
+
+## Non-Goals (deferred)
+
+- Loop dashboard panel -> v1.1
+- Auto-approve for self-improvement loop -> never (D4)
+- Tier 2 context-sizing work -> picked up by the loop itself after first tick
+- `design/context-sizing/` skeleton -> v1.1 (the loop will create it when it picks up Tier 2 work)
+
+## Requirements
+
+### R1 -- `install.sh` creates and schedules the self-improvement loop
+
+After the clone and guard registration, add:
+```bash
+# Bootstrap self-improvement loop (default-on, D21)
+python3 "$FRAMEWORK_DIR/scripts/status.py" --create-loop self-improvement \
+  --from-template self-improvement --project "$FRAMEWORK_DIR" || true
+python3 "$FRAMEWORK_DIR/scripts/status.py" --install-schedule self-improvement \
+  --interval 3600 --project "$FRAMEWORK_DIR" || true
+```
+
+The `|| true` ensures install continues even if loop creation fails (e.g. Python not yet in PATH, or schedule installation fails on an unusual platform). The loop is optional; the framework works without it.
+
+Print a message telling the user the loop is running and how to disable it:
+```bash
+echo ""
+echo "=== Self-Improvement Loop ==="
+echo "A self-improvement loop has been created and scheduled (runs every 3600s)."
+echo "It will tick against status.py --audit on this framework's own repo."
+echo "To disable: python3 ~/.automaton/scripts/status.py --pause-loop self-improvement --project ~/.automaton/"
+```
+
+### R2 -- `update.sh` bootstraps the self-improvement loop idempotently
+
+After the git pull and guard registration, add:
+```bash
+# Bootstrap self-improvement loop if not present (default-on, D21)
+if [ ! -d "$FRAMEWORK_DIR/loops/self-improvement" ]; then
+  python3 "$FRAMEWORK_DIR/scripts/status.py" --create-loop self-improvement \
+    --from-template self-improvement --project "$FRAMEWORK_DIR" || true
+  python3 "$FRAMEWORK_DIR/scripts/status.py" --install-schedule self-improvement \
+    --interval 3600 --project "$FRAMEWORK_DIR" || true
+  echo "Created self-improvement loop (default-on). --pause-loop self-improvement to disable."
+fi
+```
+
+### R3 -- Tests
+
+Write `tests/test_self_improvement_loop.py` with:
+
+1. `test_install_sh_creates_self_improvement_loop` -- verify `install.sh` contains `--create-loop self-improvement` and `--install-schedule self-improvement`
+2. `test_update_sh_bootstraps_self_improvement_loop` -- verify `update.sh` contains the idempotent bootstrap check
+3. `test_install_sh_has_opt_out_message` -- verify `install.sh` contains `--pause-loop self-improvement`
+4. `test_self_improvement_template_has_correct_fields` -- verify the template has `work_source.kind: audit`, `brakes.max_iterations: 10`, `blast_radius.use_worktree: true` (this may overlap with task 6 tests; if so, keep it as a regression guard)
+5. `test_create_loop_self_improvement_from_template` -- simulate `--create-loop self-improvement --from-template self-improvement --project <tmp>` and verify the loop dir, `loop.json`, `.state.loop`, and `.state.log` are created correctly
+
+### R4 -- Documentation updates
+
+- `CHANGELOG.md` under `[unreleased]`
+- `README.md` -- add a note in the Loop Engineering section that the self-improvement loop is default-on at install
+- `design/loops/technical.md` -- section 9 already documents the self-improvement template; add a note that install.sh creates it default-on
+
+## Verification
+
+- `bash -n scripts/install.sh scripts/update.sh` -- syntax check
+- `python3 -m pytest tests/test_self_improvement_loop.py -v`
+- `python3 -m pytest tests/ -q` -- full suite must remain green
