feat(srp): add managed camera frame planning seam

Expose native camera frame planning controls to managed pipeline assets and renderer features.

Allow managed planning to override fullscreen stage heuristics while keeping CameraFramePlan as the native execution contract.

Add scripting coverage, probe assets, and archive the phase plan after build, test, and editor smoke validation.
