- Chooses merge target by reference count or smallest ID
- Supports --auto-merge and --dry-run flags
- Added --dedupe-after flag to 'bd import' for post-import detection
- Comprehensive test coverage for duplicate detection
- Updated AGENTS.md and ADVANCED.md with usage examples

AI agents should proactively detect and merge duplicate issues to keep the database clean:
**Automated duplicate detection:**
```bash
# Find all content duplicates in the database
bd duplicates
# Automatically merge all duplicates

bd import -i issues.jsonl --resolve-collisions --dedupe-after
