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.

Use: "compact",

Short: "Compact old closed issues to save space",

Long: `Compact old closed issues using semantic summarization.
|

|
||||
Compaction reduces database size by summarizing closed issues that are no longer
|
||||
actively referenced. Full restore capability is maintained via snapshots.
|
||||
|
||||
Tiers:
|
||||
- Tier 1: Semantic compression (30 days closed, 70% reduction)
|
||||
- Tier 2: Ultra compression (90 days closed, 95% reduction)
|
||||
|
||||
Examples:
|
||||
bd compact --dry-run # Preview candidates
|
||||
bd compact --all # Compact all eligible issues
|
||||
bd compact --id bd-42 # Compact specific issue
|
||||
bd compact --id bd-42 --force # Force compact (bypass checks)
|
||||
bd compact --stats # Show statistics
|

bd compact --restore bd-42 # Restore from snapshot
