Update analysis and plan files to enhance duplicate handling and reporting

- Updated `analysis.json` with a new generation timestamp.
- Modified `plan.json` to include a new plan ID and created timestamp, and changed operation types from "no-op" to "quarantine" for specific files needing manual review.
- Enhanced the README.md to document the new `--analysis` option for generating execution plans, which now includes a human-readable summary and duplicate handling strategies.
- Introduced a new `duplicate_resolve.py` module to manage duplicate file resolution strategies.
- Improved the execution engine to support quarantine operations and added rollback functionality for quarantined files.

These changes improve the functionality of the Video Library Manager by providing better duplicate management and clearer reporting capabilities.
