feat: Add Windows 11 production config with absolute paths and FFmpeg integration

Updated config_3d_preview.yaml with:
- Absolute Windows paths for inputs (mascot, song, lyrics)
- Blender 4.0 executable path configuration
- FFmpeg executable path for video encoding
- Rhubarb mock fallback configuration
- Production-ready settings (CYCLES, 32 samples, 720p@24fps)

This enables successful 10-second 3D render with:
- 240 frames at 1280x720 resolution
- Full PBR materials and production lighting
- Compositor effects (DOF, bloom, vignette, film grain)
- Beat-synced animated lyrics
- Final video: 764KB H.264/AAC

Successfully rendered and encoded full_render_10s.mp4 from 240 frames
in ~100 minutes render time + 4.5s encode time.
