- 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for brevity - Move lib/gl_immediate_shim.js to wasm/shims/ (consolidates WASM files) - Delete docs/ directory (outdated Nov 2024 research docs) - Delete patches/ directory (already applied to fork submodules) - Delete wasm/patches/ and wasm/config/ (empty/unused) - Update all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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
