Remove unused SgrParser class

- Removed SgrParser class from lib/ghostty.ts (163 lines)
- Removed createSgrParser() method from Ghostty class
- Cleaned up unused imports (SgrAttribute, SgrAttributeTag, RGBColor)
- Updated lib/index.ts exports to remove SgrParser
- lib/ghostty.ts: 708 → 545 lines (-163 lines, -23%)

All tests passing ✅
