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

+# SPEC: Rewrite VRAM Detection as Python Script
+
+## Goal
+Replace the fragile `scripts/vram_detect.sh` with a testable Python script that produces the same JSON output.
+
+## Requirements
+1. Create `scripts/vram_detect.py` with the same CLI interface:
+   - `--model` / `-m`
+   - `--project` / `-p`
+   - Optional positional model name
+2. Preserve the human-readable output sections and the `=== JSON Output ===` block.
+3. Fix known bugs:
+   - Undefined `$headroom_pct` in manual mode.
+   - Hardcoded `"headroom": 0.25` in JSON output.
+   - GPU-counting/output ordering bug.
+   - Enforce 10KB file-read limit for API config files.
+4. Delete `scripts/vram_detect.sh`.
+5. Update references in `prompts/orchestrate.md`, `prompts/decompose.md`, `prompts/onboarding.md`, `README.md`, and `config.md` to point to the Python script.
+
+## Acceptance Criteria
+- [ ] `python scripts/vram_detect.py` runs and emits valid JSON.
+- [ ] Manual-mode headroom is read from `config.md`, not hardcoded.
+- [ ] Large API config files are read with a 10KB limit.
+- [ ] `scripts/vram_detect.sh` no longer exists.
+- [ ] All prompts/docs reference the Python script.
+
+## Non-Goals
+- Changing the recommendation algorithm.
+- Adding GPU vendor detection beyond Linux `nvidia-smi`, `lspci`, and `/proc/meminfo`.
+
+## Stop Condition
+When all acceptance criteria are met, output "CONTRACT_MET".
