feat: expose metadata from capturePhotoToFile

[mrousavy]

Summary

• extend PhotoFile with width, height, orientation, mirroring, timestamp, RAW status, and container format
• populate the same metadata on Android and iOS, with Android reading the saved file EXIF for its final dimensions and orientation
• add focused Harness coverage that compares capturePhotoToFile metadata with an in-memory Photo

Validation

• bun camera specs
• bun camera typecheck
• bunx tsc -p apps/simple-camera/tsconfig.json --noEmit
• bun lint-kotlin
• bun lint-swift
• bun lint-js (passes with 16 existing warnings)
• bun example build:android
• focused Android emulator Harness test (passes)
• iOS SimpleCamera simulator xcodebuild (passes)
• focused iOS Harness launch reached the app, but the simulator exposes no back camera, so the existing suite setup assertion stopped the test before execution
