Release v0.26.2: Hash-based staleness detection

Release v0.26.1

CRITICAL FIX (bd-53c): Reverse ZFC check prevents stale DB from corrupting JSONL

- Root cause: bd sync exports DB to JSONL before pulling from remote
- If local DB is stale, stale data would corrupt the JSONL
- Added reverse ZFC check: detects when JSONL has >20% more issues than DB
- When detected, imports JSONL first to sync database before any export
- Prevents fresh/stale clones from exporting incomplete database state

Release v0.26.0

Highlights:
- bd doctor --check-health for lightweight startup hook health checks
- --no-git-history flag to prevent spurious deletions
- gh2jsonl --id-mode hash for content-based ID generation
- Critical MCP protocol stdin fix (PR gastownhall#400)
- Git worktree staleness fix (gastownhall#399)
- Multi-part prefix support (gastownhall#398)
- bd sync commit scope fix
