Add script to compile web inject JavaScript with minification and obfuscation options

- Introduced `compile-web-script.ts` for generating JavaScript files for userscripts.
- Supports options for minification and obfuscation.
- Generates base JS, minified JS, and obfuscated userscript.
- Configurable via command line arguments and environment variables.
