Archive completed tasks, add cleanup commands, self-documenting dashboard UI

- Archive 79 completed framework-dev tasks from tasks/ -> tasks/complete/
- status.py: add --cleanup-done and --install-cleanup-schedule commands
- Add scripts/automaton-cleanup.sh for periodic task archiving
- Dashboard: rename 'Background' tab -> 'Agent', 'Cleanup' agent -> 'Completed Task Archiver', remove redundant group headers and pill badges, dim inactive agent placeholders
- .rules.md: add Self-Documenting UI Names rule
- New tests: test_cleanup_done.py, expanded test_app.py and test_task.py

-## Files Reviewed
-- `scripts/vram_detect.py` (350-line region) — `recommend_context` rewrite, `main()` extension with `--loop-mode`, JSON output additions
-- `config.md` — new `## Loop Role Models` section
-- `prompts/decompose.md` — 4k tier added, 16k floor `REFUSE` line added
-- `tests/test_context_sizing.py` — 15 new tests
-- `tests/test_vram_detect.py:76` — updated `test_recommend_context_api_model` to assert the corrected single-headroom contract
-
-## Spec Conformance (R1–R6)
-
-- R1 (single headroom): PASS — `recommend_context` returns `recommended_kb` pre-headroom, `max_peak_kb = net_kb * (100 - headroom_pct) // 100` (headroom exactly once). Confirmed by `test_recommend_context_single_headroom`.
-- R2 (no fake defaults): PASS — `else 8` / `else 6` fallbacks removed; `max(0, ...)` clamp removed. Warning emitted in non-loop mode when budget ≤ 0 or model unknown. Confirmed by `test_no_fake_defaults_when_budget_zero`, `test_no_max_zero_clamp_in_output`.
-- R3 (`--loop-mode` refuse): PASS — unknown model exits 2 ("model context window is unknown"); sub-floor budget check gated on `LOOP_MODE_CONTEXT_FLOOR_KB == 16_000`. User override is authoritative per existing `_parse_config_model` flow. Confirmed by `test_loop_mode_refuses_unknown_model`, `test_loop_mode_passes_for_known_model`.
-- R4 (JSON fields): PASS — `available_context_kb`, `loop_mode_eligible`, `loop_mode` present; `available_context_kb == max_peak_context_kb`. Confirmed by `test_json_includes_available_context_kb_and_eligible`.
-- R5 (`config.md` `## Loop Role Models`): PASS — section added verbatim with role definitions, D12/D13 references. Confirmed by `test_config_md_includes_loop_role_models_section`.
-- R6 (decompose.md 4k tier + 16k floor): PASS — `**4k VRAM**` in guidelines, `(4k VRAM)` in size targets, `≤ 16k ... REFUSE` floor line present. Confirmed by `test_decompose_md_includes_4k_tier`, `test_decompose_md_includes_16k_floor_refuse`.
-
-## Test Results
-
-- New tests: 15 passed
-- Full suite: 264 passed (one pre-existing test updated to match fixed contract; no regression)
-- Pre-existing self-consistency suite: 74 passed (no regression to prompt path enforcement or framework invariants)
-
-## Risks and Observations
-
-- One pre-existing test (`test_recommend_context_api_model`) was *asserting the bug*. Updated to assert the fixed contract. Documented inline as the reason.
-- `--loop-mode` is opt-in via CLI flag. Non-loop callers preserve prior behavior + gain a human-readable warning. Backward-compatible.
-- The override-is-authoritative path (D13) was already honored by `_parse_config_model`; no new parsing code needed.

-## Verdict
-Ship. No defects blocking transition.
