- Track pageable-host allocations through the generalized resource adaptor. - Add an absolute, unbounded-by-default host memory limit. - Reconcile pageable and pinned-host budgets and reject invalid pinned limits. - Extend statistics, Python bindings, documentation, and tests.

- Spill device chunks to host or disk and restore them on extract. - Keep disk payloads off the send path and reject send-ready disk chunks. Signed-off-by: niranda perera <niranda.perera@gmail.com>

There was no RapidsMPF-native shuffle benchmark after the cuDF shuffle bench was removed, so disk spilling could not be exercised from the C++ benchmark suite. This adds
bench_shuffle, which inserts known-size pre-partitioned buffers and times shuffle plus extract, including restore cost when chunks were spilled.cpp/benchmarks/bench_shuffle.cppwith cuDF-like-n/-p/-oscaling, MPI/UCXX launch, andBufferResource::from_options()so spill/disk behavior is env-driven.-sdiscards output for performance-only runs.rrun/UCXX shuffle, and a single-rank disk-spill path (device=0,host=0, pinned off).Depends on #1196
