f53d6f0b1b Fix runBlocking deadlock in ImageCaptureHandler 
runBlocking on the camera callback thread could deadlock when
saveBitmap() needed the main thread. Split capturePhoto() into two
phases: synchronous CPU work (decode/rotate/effect) inside the
suspendCancellableCoroutine callback, and suspend-safe saveBitmap()
after the continuation resumes in coroutine context.

e53155e8ee Add 2D focus positioning, fix rotation tracking, sync preview with effect 
2D positioning:
- Add positionX parameter to BlurParameters (was only Y before)
- Update shader with uPositionX and uPositionY uniforms
- Single-finger drag now moves focus center anywhere on screen
- Update gradient mask generation for capture

Rotation tracking:
- Remove dampening from rotation gesture (1:1 tracking)
- Rotate gesture now directly tracks finger movement
- Preview effect rotates in sync with overlay

Overlay and shader sync:
- Both now use same positionX, positionY, angle parameters
- Preview blur effect matches overlay visualization

e3e05af0b8 Fix image orientation, reduce sensitivity, fix overlay clipping 
Image orientation:
- Actually rotate captured bitmap using ImageProxy.rotationDegrees
- Save with EXIF ORIENTATION_NORMAL (bitmap already correctly oriented)
- Handle front camera mirroring

Gesture sensitivity (halved again):
- Position drag: 0.15x (was 0.3x)
- Rotation: 0.2x (was 0.4x)
- Size pinch: 0.25x (was 0.5x)
- Zoom pinch: 0.4x (was 0.6x)

Overlay drawing:
- Use screen diagonal to calculate extended geometry
- Draw lines and rectangles that extend beyond screen bounds
- Prevents clipping when tilt-shift effect is rotated

07e10ac9c3 Initial implementation of Tilt-Shift Camera Android app 
A dedicated camera app for tilt-shift photography with:
- Real-time OpenGL ES 2.0 shader-based blur preview
- Touch gesture controls (drag, rotate, pinch) for adjusting effect
- CameraX integration for camera preview and high-res capture
- EXIF metadata with GPS location support
- MediaStore integration for saving to gallery
- Jetpack Compose UI with haptic feedback

Tech stack: Kotlin, CameraX, OpenGL ES 2.0, Jetpack Compose
Min SDK: 26 (Android 8.0), Target SDK: 35 (Android 15)
