Implements two P1 tasks for the deletions manifest epic:
bd-v2x: Add deletions pruning to bd compact
- PruneDeletions function removes records older than retention period
- Default retention: 7 days (configurable via metadata.json)
- CLI --retention flag for override
- Atomic file rewrite prevents corruption
- Called automatically during all compact operations
bd-pnm: Add git history fallback for pruned deletions
- Catches deletions where manifest entry was pruned
- Uses git log -S to search for ID in JSONL history
- Batches multiple IDs for efficiency (git -G regex)
- Self-healing: backfills manifest on hit
- Conservative: keeps issue if git check fails (shallow clone)
Tests added for both features with edge cases covered.

- Return LoadResult struct instead of multiple values, with Warnings slice
for testability (no more hardcoded stderr output)
- Add ID validation in AppendDeletion to prevent invalid records
- Add Sync() call in AppendDeletion for durability
- Document that timestamps may lose sub-second precision
- Document that empty slice in WriteDeletions clears all deletions
- Add test for empty ID validation
