jgrusewski 2d704eaa07 fix: backward cuBLASLt uses heuristic algo — AlgoGetIds selects graph-incompatible algo on H100
AlgoGetIds picks algorithms by ID order. On H100 (SM90), the first
valid algo uses split-K/stream-K with internal workspace allocation
that silently produces zero output when replayed via CUDA Graph.
The heuristic selects graph-safe algorithms by design.

Also removes FOXHUNT_NO_GRAPH temp env var and raw DtoH diagnostic probe.
