houdini-camera-light

Typed camera and light authoring for agents. All tools are affinity: main. View tools (frame_view, get_view_state) are UI-aware: in a headless hython session they return a structured warnings payload with framed: false / ui_available: false instead of failing.

Tool groups

• camera: list_cameras, create_camera, update_camera.
• view: frame_view, get_view_state.
• light: create_light, update_light.

Tracer-bullet flow

1. create_camera(parent_path="/obj", name="shotcam", focal=50, resolution=[1920,1080])
2. create_light(light_type="distant", intensity=2.0, color=[1,0.95,0.9])
3. frame_view(camera_path="/obj/shotcam", node_path="/obj/geo1")
4. get_view_state() → confirm active_camera
5. hand off to houdini-render (capture_viewport / render)

Light/camera parameter writes are defensive (set only when the parm exists), so they tolerate hlight::2.0 vs older hlight and Karma/Mantra camera variants.
