Initial FlareSolverr Cloudron package

- Add CloudronManifest.json with app metadata
- Create Dockerfile with multi-stage build
- Install Google Chrome (Chrome for Testing) since Ubuntu Noble doesn't have chromium package
- Install required Chrome dependencies (libatk, libgtk, etc.)
- Add start.sh script with Xvfb setup for headless Chrome
- Copy entire Chrome installation directory for proper resource access
- Add .gitignore and update README with installation instructions
