feat: Tier 4 - Production Finishing (8 nodes, v0.6.0)
Complete production finishing toolkit with 8 professional nodes:
1. Crop - Aspect ratio presets + soft edges
- 7 industry-standard aspect ratios (16:9, 2.39:1, etc.)
- 3 feather modes: linear, smooth (smoothstep), gaussian
- Center crop mode for quick framing
2. Exposure - Photographic f-stops control
- Per-channel stops (R/G/B) for creative grading
- Highlight rolloff to prevent blown highlights
- 3 response curves: linear, logarithmic, filmic (ACES-like)
3. Vignette - Lens vignetting effects
- 3 shapes: circular, oval, rectangular
- 4 falloff curves: linear, quadratic, cubic, smooth
- Color tinting for stylistic edges
4. Grain - Film grain & texture
- 4 grain types: film, digital, organic, halftone
- Luminance-dependent distribution
- Per-channel intensity control
5. HueSatVal - Direct HSV manipulation
- Selective hue ranges (reds, yellows, greens, etc.)
- Range softness for smooth transitions
- Preserve luminance mode
6. Denoise - Edge-preserving noise reduction
- 3 algorithms: bilateral, median, gaussian
- Detail preservation control
- Luma/chroma separation
7. LUT - 1D/3D color lookup tables
- Industry-standard .cube file support
- Trilinear interpolation for 3D LUTs
- LUT caching for performance
8. CornerPin - 4-point perspective transform
- Homography calculation (DLT/SVD)
- 3 filter modes: bilinear, bicubic, nearest
- Inverse transformation support
Total: 34 production nodes (9 T1 + 8 T2 + 1 Crypto + 8 T3 + 8 T4)
Updated documentation: NODE_SPECIFICATIONS.md, README.md
Version bump: 0.5.0 → 0.6.0
