Extend OVRTX interactive edits

When to Use

Use when implementing Blender depsgraph extraction, typed USD value conversion, live runtime submission, durable write routing, topology fallback, user diagnostics, and tests.

Boundary

Work in the distributed source checkout and use documented runtime interfaces. Prove a missing runtime capability with the escalation probe before declaring an add-on-only implementation impossible.

Preserve the architecture

Route every edit through this pipeline:

Blender depsgraph signal → InteractiveEdit → EditPlan → InteractiveEditWorkflow → RuntimeScheduler or durable USD write → OvrtxSessionUpdatePort.
