Replace the single-pass 9-tap directional blur with a three-pass
pipeline: passthrough (camera→FBO), horizontal blur (FBO-A→FBO-B),
vertical blur (FBO-B→screen). This produces a true 2D Gaussian with
a 13-tap kernel per pass, eliminating the visible banding/streaking
of the old approach.
Key changes:
- TiltShiftRenderer: FBO ping-pong with two color textures, separate
fullscreen quad for blur passes (no crop-to-fill), drawQuad helper
- TiltShiftShader: manages two programs (passthrough + blur), blur
program uses raw screen-space angle (no camera rotation adjustment)
- tiltshift_fragment.glsl: rewritten for sampler2D in screen space,
aspect correction on X axis (height-normalized), uBlurDirection
uniform for H/V selection, wider falloff (3x multiplier)
- New tiltshift_passthrough_fragment.glsl for camera→FBO copy
- TiltShiftOverlay: shrink PINCH_SIZE zone (1.3x, was 2.0x) so
pinch-to-zoom is reachable over more of the screen
- CameraManager: optimistic zoom update fixes pinch-to-zoom stalling
(stale zoomRatio base prevented delta accumulation)
Bump version to 1.1.3.

Accompanist Permissions (0.36.0) is deprecated and experimental. Migrate
to the stable ActivityResultContracts.RequestPermission /
RequestMultiplePermissions APIs already available via activity-compose.
Adds explicit state tracking with a cameraResultReceived flag to
correctly distinguish "never asked" from "permanently denied" — an
improvement over the previous Accompanist-based detection.
Bump version to 1.1.2.
