Jason 69c0a09604 refactor(cleanup): remove dead code and optimize Option checks
- Remove 5 unused functions that were left over from migration refactoring:
  - get_archive_root, ensure_unique_path, archive_file (config.rs)
  - read_config_text_from_path, read_and_validate_config_from_path (codex_config.rs)
- Simplify is_v1 check using is_some_and instead of map_or for better readability
- Remove outdated comments about removed functions

This eliminates all dead_code warnings and improves code maintainability.
