Subject: feat(scene1): replace ad-hoc camera with CameraParams uniform
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Build camera via mat4::look_at + inverse in scene1_effect.cc, upload as
CameraParams at binding 3. Shader uses getCameraRay() from camera_common.
Enable camera_common snippet registration in shaders.cc.

handoff(Claude): Scene1 camera now driven by CameraParams uniform; fov=TAU/6 (60° vFOV) matches original tan(PI/3) parameterization.
