- Fixed bug where daily_snapshots were recalculated from scratch, losing historical data when JSONL files aged out
- Now only updates snapshots for dates with current records, preserving all historical data
- Migrated from manual sys.argv parsing to typer framework for better UX
- Updated command syntax: claude-goblin <command> instead of --<command> flags
- Updated hooks to use new command syntax with backward compatibility
- Version bump to 0.1.1
