README updates:
- Document WebGL GAL integration in kicad/common/gal/webgl/
- Add Test Scripts section with all 4 GAL scripts
- Add WebGL Integration section explaining the architecture
- Update Directory Structure to include wasm/ and baseline-webgl/

Establish baseline screenshots for WebGL GAL implementation before
migrating it from test harness into KiCad's build system.
Current status: 7/27 scenarios passing (20 different from native):
- Alpha-blending: FIXED (blending now correct)
- Transform-API: EXCLUDED (dead code)
- Other scenarios: Work in progress
This baseline will be used by test-gal-webgl.sh to detect regressions
during the migration process. Goal is to preserve current rendering
fidelity while integrating WebGL GAL into KiCad source tree.
