Module handle 

Handle and RNG primitives for oxicuda-graphalg.

Mirrors the pattern of oxicuda-tn and oxicuda-cvx.

Provides:

• SmVersion tagging GPU compute capability.
• LcgRng a minimal LCG (MMIX variant) pseudo-random generator that uses bit 32 for boolean sampling (LCG low bits have period defects).
• GraphalgHandle bundling SM version and a seeded RNG.

Structs

GraphalgHandle

Top-level graph algorithm computation handle bundling SM version and a seeded RNG.

LcgRng

Minimal LCG (MMIX variant) pseudo-random number generator.

SmVersion

SM compute capability version (e.g. 75 for SM 7.5, 100 for Blackwell SM 10.0).
