Phase 1 critical fixes addressing three high-priority issues: Issue #36 - Windows IPC backend crash (os.getuid not available): - Add platform detection to skip Unix-specific socket paths on Windows - Use hasattr check before calling os.getuid() - Windows now uses auto-detect fallback (named pipes) - Maintains full Unix socket support on Linux/macOS Issue #37 - Windows schematic file creation broken: - Generate unique UUIDs instead of invalid all-zeros UUID - Add explicit UTF-8 encoding for cross-platform compatibility - Force Unix line endings (LF) to prevent Windows CRLF issues - Update template file with valid placeholder UUID - Fix hardcoded /tmp/ paths in wire_manager.py and pin_locator.py Issue #35 - JLCPCB download limited to 100 parts: - Change batch_size from 1000 to 100 to match tscircuit API limit - Remove premature loop termination when batch < batch_size - Add documentation explaining API limitation - Expected result: Full ~2.5M part catalog download (40-60 minutes) All changes maintain backward compatibility and include detailed comments.
