chore: enhance output and verification in PR plugin generation script

- Improved the `generate-pr-plugin.sh` script to provide detailed output during tarball examination and file extraction.
- Added a summary of installed files, including counts of modified and new files, to enhance visibility and verification of the installation process.
- Updated echo statements for clarity and consistency in reporting file processing status.
