Enhance project structure and add new files for enrichment and analysis

- Updated AGENTS.md to reflect changes in CLI commands and module organization, including the addition of an enrichment step and new functional modules.
- Introduced analysis.json, identities.json, inventory.csv, and plan.json to support enriched metadata and execution planning.
- Added CODE_IMPROVEMENTS.md to document identified code issues and proposed solutions for future enhancements.
- Updated README.md to include new enrichment features and configuration options.
- Removed unused dependency on ffmpeg-python from pyproject.toml.

These changes improve the overall functionality and maintainability of the Video Library Manager project.
