Snapshots defeated the entire purpose of compaction - if we're keeping
the original content, we're not actually saving any space. Compaction
is about graceful memory decay for agentic databases, not reversible
compression.
Removed:
- CreateSnapshot/GetSnapshots/RestoreFromSnapshot from storage
- --restore flag and functionality from bd compact command
- All snapshot-related tests
- Snapshot struct and related code
The database is ephemeral and meant to decay over time. Compaction
actually reduces database size now.
Closes bd-260 (won't fix - conceptually wrong)
Closes bd-261 (already done in bd-259)
- Add Compactor with CompactTier1 and CompactTier1Batch methods
- Single issue and batch compaction with 5 concurrent workers
- Dry-run mode for testing without API calls
- Smart size checking: keeps original if summary is longer
- Improved Haiku prompts to emphasize compression
- Add ApplyCompaction method for setting compaction metadata
- Comprehensive tests including API integration tests
- All tests passing
