rendergraph: correct transient-resource aliasing with pooled placement
...
Lifetimes derive from the real dependency ordering (retained DAG +
compile-time happens-before closure), not command-index intervals.
Aliasing is restricted to the single-queue contract; alias reuse is
synchronized with memory/image barriers anchored at first-use commands.
- renderer_device: aliasable shared allocations (CAN_ALIAS), memory-
requirements queries incl. dedicated hints, offset-aware
bind_buffer/image_memory2, grouped bind under one allocator lock
- renderer_resources: unallocated resource creation, requirements
cached in Allocation::Unmanaged (OnceLock), MemoryGroup pooling with
intersecting memoryTypeBits, bind-time validation
- renderer_rendergraph: retained dependency DAG, happens_before
closure, batch lifetimes, Placement type, plan_placements with
pooled aliasing (first-fit over offset-sorted ranges, pool classes
split by bufferImageGranularity), alias-barrier construction,
placement/bind error variants
- perf: quadratic compile/resolve paths eliminated (per-resource
indexing, frontier caching, backward-scan prune, cached recording
index, recorder scratch reuse); single requirements query per
resource through plan/validate/bind
- design plan + GPU-gated validation tests

feat: migrate GPU memory allocator from gpu-allocator to VMA (vk-mem)
...
- Replace gpu-allocator with vk-mem 0.5.0 (VMA 3.3.0) in renderer_device
- Add public GpuAllocation wrapper, MemoryLocation, AllocationDesc, and
allocate_for_buffer/image + bind_buffer/image_memory helpers
- Restrict CPU-mapped allocations to HOST_VISIBLE|HOST_COHERENT memory types
- Handle guards: raw buffer/image handles owned before allocation so failure
paths never leak
- Use renderer_device::device::MemoryLocation across renderer, renderer_resources,
and renderer_rendergraph; remove all gpu-allocator dependencies
- Error on dedicated allocation below Vulkan 1.1 instead of silent downgrade
- Add Send/Sync asserts, coherent-mapping and dedicated-allocation validation
tests; update AGENTS.md docs
