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

-# Code Review: fix-vram-model-prefix-match
-
-## Reviewed Files
-- `scripts/vram_detect.py` (`_lookup_model_context()`, `_KNOWN_MODEL_SUFFIXES`)
-
-## Changes
-Replaced raw `startswith()` with three-tier matching: exact match, `:` separator (Ollama tags), and `-` separator with known instruction-tuning suffix whitelist.
-
-## Analysis
-- **Correctness**: The three-tier approach correctly handles all test cases:
-  - `deepseek-r1:7b` matches via `:` separator ✓
-  - `llama-3.1-8b-instruct` matches via `-` + `instruct` suffix ✓
-  - `phi-4-mini-instruct` rejected (`mini` not in suffixes) ✓
-  - `gpt-4o-foo-unknown` rejected (`foo` not in suffixes) ✓
-  - `phi-40` rejected (no separator) ✓
-- **Edge cases**: `gpt-4-turbo` is in the dict directly, so it matches via exact match (checked before `gpt-4` due to length-descending sort)
-- **Maintainability**: The suffix whitelist is explicit and easy to extend
-
-## Verdict: PASS
-
-The fix is well-structured, handles all edge cases correctly, and is properly tested.
