fix: address code quality issues, validation gaps, and add test coverage
Phase 1 - Code Quality:
- Rename script/script.rs to script/types.rs (module inception fix)
- Apply Clippy lint fixes (is_none_or, is_some_and, char patterns, etc.)
- Implement FromStr for CatalogFile and Category
- Add filtered_targets() and filtered_repos() helpers to Config
Phase 2 - Validation & Error Handling:
- Add validate_repo_identifier() for GitHub shorthand validation
- Fix first-run setup to fail gracefully if no targets configured
- Improve import to collect failures and only save on success
- Add AssetInstallResult for detailed install failure tracking
- Fix lockfile timestamp documentation (Unix epoch, not RFC 3339)
- Add comprehensive RevType heuristics documentation
- Add checkout warning when local modifications will be discarded
Phase 3 - Test Coverage:
- Add tempfile, assert_cmd, predicates dev dependencies
- Add security tests (symlink boundaries, copy mode)
- Add git operations tests (init, head_commit, RevType parsing)
- Add lockfile tests (roundtrip, lock/get operations)
- Add CLI integration tests (help, validation, duplicates)
- Add config validation tests for new helper methods
All 48 tests pass, clippy clean, release build verified.
