Lemenzo Gallery v1.4 - production hardening

Editor correctness fixes
- Full-resolution export now decodes the original media again at native resolution.
- The 2048 px bounded bitmap is used only for interactive preview.
- Rotate/flip are stored as non-destructive edit operations and replayed for export.
- Crop presets are non-destructive state and no longer crop already-cropped pixels.
- Geometry and color adjustments render in one output allocation to reduce peak memory.
- JPEG, PNG and WebP output bytes use matching MIME types/extensions.
- Alpha-capable PNG content is preserved as PNG; WebP is exported losslessly.
- HEIF/AVIF and other formats without a public Bitmap encoder fall back truthfully to high-quality JPEG.
- Camera/date/lens/GPS EXIF metadata is preserved best-effort; stale orientation is normalized.
- Edited copy is saved alongside the source MediaStore relative path when available, with Pictures/Lemenzo fallback.
- Editor state survives Activity recreation.
- Full-resolution export failure never modifies the original and cleans up pending MediaStore rows.

Privacy hardening
- INTERNET permission remains absent.
- Explicit Android data extraction rules exclude app data from cloud backup and device transfer.

Validation in this package
- ZIP integrity checked.
- All XML parses successfully.
- Manifest Activity classes resolved to source files.
- Java R.string/R.id references checked against resources.
- No INTERNET permission found.

A successful build inside the actual LemenzoOS Android 16 tree and runtime tests on target Pixels remain mandatory release gates.
