## Summary by CodeRabbit

- **New Features**
- Added a script to automatically prepare UI components before running
the build watch process in the web app.
- **Bug Fixes**
- Improved build and release processes to ensure directories are
properly cleaned and created, preventing potential errors during Docker
operations.
- **Chores**
- Updated build watch scripts for faster development feedback and more
efficient parallel execution.
- Refined Docker Compose configuration to use the correct release
directory for plugin builds.
- Introduced a new script to streamline and centralize file watching and
build triggering in the plugin system.
