feat: extend render options with resolution, bounces, clamping, denoiser, output format

Added properties:
- Resolution override (width, height, percentage)
- Min samples + time limit for adaptive sampling
- Denoiser type (OIDN / OptiX) + denoise input passes
- Individual light bounces (diffuse, glossy, transmission, transparent, volume)
- Clamping (direct, indirect)
- Film transparent toggle + pixel filter width
- Output format (PNG, JPEG, TIFF, EXR, EXR Multilayer)
- Color depth (8/16 bit)

Version bump to 2.0.0
