v0.0.5 of flutter_native_vision_camera

High-performance Flutter FFI camera plugin with zero-copy preview textures, integrated MLKit/Vision barcode scanning, and low-latency native frame access for real-time on-device vision.

The GIFs live in the repo and are referenced by raw URL, so they're excluded from the published package.
