Add detailed debugging output for WASM build in CI

- Add clear section markers with ===== for visibility
- Show current directory and file listings at each step
- Exit with error if build or copy fails
- Use find to locate WASM files if copy fails

This will help diagnose why the WASM file is not being included in artifacts.
