feat: Add subdirectory hosting support and fix asset path resolution

- Update README with comprehensive subdirectory hosting instructions and BASE_URL configuration guide
- Convert absolute asset paths to relative paths in index.html for proper subdirectory deployment
- Update all worker script imports to use relative paths instead of absolute paths
- Fix favicon and image references to work correctly when hosted in nested directories
- Normalize whitespace and formatting across worker files for consistency
- Update vite.config.ts to properly handle BASE_URL configuration for subdirectory deployments
- Ensure all tool pages and logic files maintain compatibility with subdirectory hosting
- Enable BentoPDF to be deployed at any URL path (e.g., example.com/tools/bentopdf/) without breaking asset loading
