- Implemented common transient page allocator in RHICore.
- Implemented XBox specific GPU page table mapping allocator.
- Extended RDG insights to support viewing heap visualization or page pool visualization.

- Refactored RDG to support free-threaded execution of passes.
- Refactored renderer to use specific RHI command list variants in pass lambda. Immediate command list passes are forced to stay on the render thread, while other variants can be parallelized.

- New Drain() method on FRDGBuilder; will flush all pending work.
- Drained passes are not culled; resource lifetimes are extended; async compute fences are optimized as best as possible but fence joining may occur after the drain.
- Batch up and pre-build all resource transitions. This is a prerequisite for parallel command lists.
- Removed ServiceLocalQueue passes with built-in RDG AddDispatchHint().
#jira UE-114622
[CL 16393495 by zach bethel in ue5-main branch]
- Replaced legacy transient support from RDG and replaced with new API.
- Reworked acquire / discard operations a bit and added RHI validation to track correctness.
- Reworked RDG barrier batching to include acquire / discard operations.
- Hardened render pass merging logic and expanded to support lifetime extension of transient resources.
- Added transient tag to RDG insights to track which resources are transient.
