64abd87a9e Add wide gamut color support with OKLCH and LAB formats 
Implements modern wide gamut color formats with CSS Color Module Level 4
gamut mapping, addressing PR feedback with Go implementation, performance
benchmarks, and reorganized documentation.

Features:
- OKLCH (perceptually uniform color space)
- CIE LAB (device-independent color space)
- CSS Color 4 compliant gamut mapping algorithm
- Inline comment support in color config parsing

Addressing PR Feedback:

1. Go Implementation (tools/utils/style/):
   - Complete OKLCH and LAB parsing with gamut mapping
   - Matches Python implementation structure
   - Comprehensive test suite (all tests passing)
   - Performance benchmarks showing acceptable overhead

2. Performance Benchmarks:
   - OKLCH: ~4.6 µs/op
   - LAB: ~1.5 µs/op
   - 10 mixed colors: ~13 µs total
   - Typical config (50 colors): <0.5ms startup impact

3. Documentation Reorganization:
   - Moved detailed color docs to docs/wide-gamut-colors.rst
   - Configuration docs now link to separate documentation
   - Reduces size of main configuration documentation

Gamut Mapping:
- Binary search chroma reduction from CSS Color Module Level 4
- Preserves lightness and hue while reducing chroma for out-of-gamut colors
- Uses deltaE OK (JND threshold: 0.02) for perceptual difference
- Ensures graceful degradation on sRGB displays

Python Implementation:
- parse_oklch(): OKLCH color parsing with gamut mapping
- parse_lab(): CIE LAB parsing with gamut mapping via OKLCH conversion
- lab_to_oklch(): LAB to OKLCH conversion for consistent gamut mapping
- oklch_to_srgb_gamut_map(): CSS Color 4 gamut mapping algorithm
- srgb_to_oklab(): Reverse conversion for deltaE calculations
- deltaE_ok(): Perceptual color difference in OKLab space

Go Implementation:
- colorspaces.go: All color space conversions and gamut mapping
- wrapper.go: ParseColor() updated to support OKLCH and LAB
- Comprehensive test coverage with benchmarks
- Matches Python implementation behavior

Robustness:
- NaN and infinity validation in all color parsing functions
- Defense-in-depth with validation at parsing and gamut mapping levels
- Returns None/error for invalid input (consistent error handling)
- Validates before clamping operations to prevent NaN propagation

Files changed:
- Python: kitty/rgb.py, kitty_tests/datatypes.py (+250 lines)
- Go: tools/utils/style/colorspaces.go, wrapper.go (+350 lines, tests)
- Docs: docs/wide-gamut-colors.rst (moved from inline)
- Config: kitty/options/definition.py (simplified, links to docs)

- CSS Color Module Level 4: https://www.w3.org/TR/css-color-4/
