Adding optional camera vision to an AI chat app

Scowld can send a camera frame as context with a message. The design goals were privacy-first:

• Frames are captured on-device and sent only when you send a message.
• They go only to the provider you configured.
• Nothing is written to the photo library.
• Vision is opt-in and can be revoked in Settings/iOS.

Multimodal without the creep factor. Source: https://github.com/apoorvdarshan/scowld
