refactor(rules): replace unwrap() with explicit error handling and propagate errors safely

Browse Source 
- Replace Option::unwrap() with pattern matching in add_rule label check
- Handle home directory resolution failures with proper Error types
- Add directory creation in save() to ensure parent directories exist
- Replace chrono unwraps with ? operator for date calculations
- Use unwrap_or with sensible defaults for parsing edge cases
- Keep unwrap in test code where immediate failure is desired
- All existing functionality preserved; no API changes
