fix: filter Windows-specific wheels from PEX lock for Linux/Mac targets

- Add platform filtering to exclude Windows wheels (Win32, WinAmd64, WinArm64, WinIa64)
- Import uv_platform_tags::PlatformTag for platform detection
- Only include platform-compatible artifacts in PEX lock file
- Fixes "Failed to resolve compatible artifacts" error for Linux targets

This prevents Windows-only packages like pywin32 from being included
in PEX lock files targeting Linux/Mac systems.
