ADR skill, status vocab, and security log fixes
- Enhanced `adr-author` skill and ADR template based on first use: clarified opinion sharing, cross-referencing, index updates, and parallel session handling; rewrote ADR template pointer and added first repo-wide ADR.
- Updated skill loading: only `docs-discovery` and `docs-check` pre-loaded; others lazy-loaded; removed `version` from SKILL.md frontmatters.
- Simplified issue/TODO status to `Open`, `InProgress`, `Closed`; updated archiving logic and migrated all entries.
- Added forward-slash glob pattern rule to `docs-discovery/SKILL.md`.
- Closed LOG-I-9 and LOG-I-10: DEBUG-gated sensitive log lines, fixed typo, and cross-referenced new ADR.
- Various documentation and index improvements.
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
