Subject: Add flexible module loading and complete file embedding

 - Support any folder structure (no hard-coded folders)
 - Embed all file types recursively from any folder
 - Fix require() dot-to-slash conversion for embedded modules
 - Clean build folder for fresh builds every time
 - Generate empty headers for Lua-only projects

 Backward compatible with existing projects.
