Simplify Status field; add docs-archive skill & archiving
- Reduced Status field values in issues/TODOs to Open, InProgress, Closed; updated all affected entries to new convention
- Introduced docs-archive skill for rotating Closed entries into year-bucketed archive files; process is user-invoked or LLM-suggested, never automatic
- Expanded docs-discovery and protocol documentation to clarify archive file handling and on-demand loading
- Updated session setup: only reactive skills pre-loaded, user-gated skills now lazy-loaded for token efficiency
- Clarified and documented Status update workflow, archive eligibility, and lifecycle
- Updated all relevant issue/TODO files to match new Status conventions and archival process
