Implement optional single-image intake, Signal ingestion, and multimodal vision analysis

- Add image intake service with format validation (JPEG, PNG, WebP) and EXIF/GPS stripping
- Enforce strict single-image rule across Web and Signal attachment channels
- Implement token-optimized vision downscaling and JPEG compression
- Add IMAGE_CONTEXT pipeline stage with OmniRoute vision routing and resilient failover
- Seed and manage versioned idea-image-interpreter prompt in catalog
- Update Web UI with responsive image picker, preview chip, and Visual Context tab
- Add comprehensive automated test suite in test_image_intake.py
- Update README and Labyricorn devlog
