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 🤖 Generated with Claude Code https://claude.com/claude-code Co-Authored-By: Claude <noreply@anthropic.com>
