This commit addresses multiple critical issues in pattern rendering and coordinate handling:
1. Fixed Y-axis offset accumulation in penParser.ts
- Corrected sign extension logic for 16-bit signed coordinates
- Changed to interpret full 16-bit value as signed before shifting
- Prevents coordinate drift and offset accumulation
2. Fixed color assignment for tack stitches in patternConverter.worker.ts
- Added detection for small finishing stitches after COLOR_CHANGE commands
- Assigns tack stitches to correct (previous) color instead of new color
- Uses conservative pattern matching (< 1.0 unit, followed by JUMP)
3. Made jump stitches visible in pattern preview (KonvaComponents.tsx)
- Render jump stitches in thread color instead of gray
- Use dashed pattern [8, 4] to distinguish from regular stitches
- Set appropriate opacity (0.8 completed, 0.5 not completed)
- Fixed critical bug: include previous position in jump groups to create proper line segments
4. Updated konvaRenderers.ts for consistency
- Applied same jump stitch rendering logic
- Ensures consistent behavior across rendering methods
