Fixes from code review:
1. **Data completeness**: Now migrates events (including comments)
and all config values, not just issues/labels/deps
2. **formatJSONArray**: Fixed to use JSON encoding for waiters field
to match Dolt schema (was using comma-separated format)
3. **Cleanup on failure**: Removes partial Dolt directory or SQLite
files if import fails mid-way
4. **Progress indicator**: Shows "Importing issues: N/M" for large
migrations (100+ issues)
5. **Code deduplication**: Extracted common logic into:
- migrationData struct
- storageReader interface
- extractFromStore() shared extraction
- Helper functions for output formatting
6. **Improved dry-run output**: Now shows event count and config
key count in migration plan

Add `bd migrate --to-dolt` and `bd migrate --to-sqlite` commands for
migrating between SQLite and Dolt storage backends.
Features:
- `--to-dolt`: Migrate from SQLite to Dolt backend
- Creates backup of SQLite database before migration
- Imports all issues, labels, and dependencies
- Updates metadata.json to use Dolt backend
- Preserves JSONL export configuration
- `--to-sqlite`: Escape hatch to migrate back to SQLite
- Exports all data from Dolt to new SQLite database
- Updates metadata.json to use SQLite backend
Both commands support:
- `--dry-run` flag to preview changes
- `--yes` flag for automated/scripted usage
- `--json` flag for machine-readable output
- Non-cgo stub for builds without CGO support
This implements Part 7 (Migration Tooling) of DOLT-STORAGE-DESIGN.md.
