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)
