da5493bac0 Remove snapshot/restore functionality from compaction 
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)

35a4cba829 Add bd compact CLI command (bd-259) 
Implements the compact command with all required features:
- --dry-run: Preview compaction with size estimates
- --all: Process all eligible candidates
- --id: Compact specific issue
- --force: Bypass eligibility checks (requires --id)
- --stats: Show compaction statistics
- --tier: Select compaction tier (1 or 2)
- --workers: Configure parallel workers
- --batch-size: Configure batch processing
- Progress bar with visual feedback
- JSON output support
- Proper exit codes and error handling
- Summary reporting (count, bytes saved, reduction %, time)

Includes additional test coverage for compaction and snapshot operations.
