feat: Week 1 complete - Linux support + IPC API prep

🎉 Major v2.0 rebuild kickoff - Week 1 accomplished!

## Highlights

### Cross-Platform Support 🌍
- ✅ Linux primary platform (Ubuntu/Debian tested)
- ✅ Windows fully supported
- ✅ macOS experimental support
- ✅ Platform-agnostic path handling (XDG spec)
- ✅ Auto-detection of KiCAD installation

### Infrastructure 🏗️
- ✅ GitHub Actions CI/CD pipeline
- ✅ Pytest framework with 20+ tests
- ✅ Pre-commit hooks (Black, MyPy, ESLint)
- ✅ Automated Linux installation script
- ✅ Enhanced npm scripts

### IPC API Migration Prep 🚀
- ✅ Comprehensive migration plan (30 pages)
- ✅ Backend abstraction layer (800+ lines)
- ✅ Factory pattern with auto-detection
- ✅ SWIG backward compatibility wrapper
- ✅ IPC backend skeleton ready

### Documentation 📚
- ✅ Updated README (Linux installation)
- ✅ CONTRIBUTING.md guide
- ✅ Linux compatibility audit
- ✅ IPC API migration plan
- ✅ Session summaries
- ✅ Platform-specific config templates

## Files Changed

- 27 files created
- ~3,000 lines of code/docs
- 8 comprehensive documentation pages
- 20+ unit tests
- 5 abstraction layer modules

## Next Steps

- Week 2: IPC API migration (project.py → component.py → routing.py)
- Migrate from deprecated SWIG to official IPC API
- JLCPCB/Digikey integration prep
