Reorganize project structure for clarity

- Rename tests/wasm-app/ to tests/apps/ for brevity
- Move lib/gl_immediate_shim.js to wasm/shims/ (consolidates WASM files)
- Delete docs/ directory (outdated Nov 2024 research docs)
- Delete patches/ directory (already applied to fork submodules)
- Delete wasm/patches/ and wasm/config/ (empty/unused)
- Update all file references in scripts, configs, and documentation
- Update .gitignore for new tests/apps/ paths

Verified both build workflows pass:
- wxWidgets tests: 255 passed
- Docker KiCad build: completed successfully
