Introduce a formal ScriptableRendererData setup seam so renderer feature attachment is owned by renderer data instead of renderer constructors pulling feature caches.
Route lifecycle and reuse probes through the new setup path, lock the non-public setup seam in the API surface probe, and update scripting expectations accordingly.
Promote ScriptableRenderer renderer-recording context methods to the primary Universal execution seam and route the renderer-driven pipeline through that seam.
Update managed probes and scripting expectations to cover the new non-public renderer recording contract, and archive the completed phase plan.
- derive fullscreen stage planning from pipeline render-graph support
- trim planning-only APIs from the managed SRP bridge and public surface
- update probes and tests to lock the slimmer SRP API boundary
