Move Pyodide/PyStitch pattern conversion to a dedicated Web Worker for
non-blocking UI performance. Pyodide now loads in the background on app
startup with real-time progress indicator showing download and initialization
status.
Key changes:
- Create patternConverter.worker.ts with full PES to PEN conversion logic
- Add patternConverterClient.ts singleton for worker management
- Implement progress tracking (0-100%) with step descriptions
- Add inline progress bar in FileUpload component with contextual messaging
- Configure COEP headers for Electron to support Web Workers
- Pass dynamic asset URLs to worker for file:// protocol support
- Update UIStore with progress state management
- Simplify pystitchConverter.ts to delegate to worker client
Benefits:
- Truly non-blocking UI (heavy Python/WASM runs off main thread)
- Real progress feedback during 15MB Pyodide download
- Works in both browser and Electron (dev and production)
- Faster app startup perception with background loading
- Better UX with "waiting" state if user clicks before ready

Correct the encoding of TRIM commands to use the proper bit flag (bit 1)
instead of incorrectly treating them the same as JUMP commands (bit 0).
The PEN format uses two separate flags in the Y-coordinate low byte:
- Bit 0 (0x01): FEED_DATA - Jump stitch (move without stitching)
- Bit 1 (0x02): CUT_DATA - Trim/cut thread command
Previously, both JUMP and TRIM commands were encoded with bit 0, which
prevented the machine from distinguishing between jumps and thread cuts.
Changes:
- Add PEN_CUT_DATA constant (0x02) for TRIM commands
- Update encoding logic to set bit 0 for JUMP (cmd=1)
- Update encoding logic to set bit 1 for TRIM (cmd=2)
- Add detailed comments explaining the PEN format flags
- Document that Y-coordinate flags can be combined
- Document that X-coordinate flags are mutually exclusive
This fix ensures thread cutting happens when intended, matching the
behavior of the original C# implementation in the Asura app.
