Viktor Vaczi a26b40c063 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- Delete docs/ directory (outdated Nov 2024 research docs)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

Two Build Workflows

1. KiCad Build (Docker)

Full KiCad PCBnew build using Docker:

# Build KiCad WASM
./docker/build.sh

# Copy output to test directory
./tests/scripts/setup-kicad-wasm.sh

# Run KiCad tests
cd tests && npm install && npm run test:kicad

Output: output/pcbnew.js, output/pcbnew.wasm

See build.md for detailed build documentation.

2. wxWidgets Test Apps (Local)

Build standalone wxWidgets test apps for feature testing:

# Build wxWidgets for WASM
./scripts/build-wxuniversal-wasm.sh

# Build test apps
./scripts/build-wasm-test.sh

# Run wxWidgets tests
cd tests && npm install && npm test

Output: tests/apps/standalone/

Prerequisites

For KiCad Build (Docker)

Docker Desktop with 16GB+ RAM allocated
10+ GB disk space for build cache

For wxWidgets Build (Local)

Emscripten SDK 4.0+
Node.js 18+ (for tests)

# macOS
brew install emscripten node

# Initialize submodules
git submodule update --init --recursive

Testing

cd tests
npm install

# Run all tests
npm test

# Run specific tests
npm run test:kicad          # KiCad tests only
npx playwright test menu    # Menu tests only

See tests/README.md for test documentation.

Current Status

wxWidgets WASM: Core widgets working (menus, dialogs, grids, trees, OpenGL)
KiCad PCBnew: Builds and loads in browser, canvas rendering working
In Progress: Testing wxWidgets features used by KiCad
