Flutter Image Picker Production Engineering

Treat image_picker as a thin platform-mediated media acquisition boundary. It is not durable storage, a camera framework, a media-library manager, or a security validator. Use this pipeline:

acquire
→ recover lifecycle result
→ validate
→ optionally transform
→ preview
→ persist only when durable ownership is required
→ upload/consume
→ clean application-owned artifacts

Optimize the whole pipeline, not just the picker call.
