Adds new flags `--drawj2d-jar` and `--install-deps` to handle OCR dependencies
Automatically checks for required tools (unzip, Java, drawj2d.jar)
Installs missing system packages when `--install-deps` is used
Updates documentation with OCR setup examples
The implementation includes dependency checking that can be skipped with `--skip-deps`
when OCR functionality is not needed. The installer now copies and configures
drawj2d.jar if provided, and updates the plugin's data.json accordingly.
