Detailed Description

Phase 8 tests for ca-rng.H.

Coverage:

• splitmix64 avalanche (small inputs spread across all 64 bits).
• cell_seed is sensitive to every coordinate component, the step index and the master seed.
• Per_Thread_RNG::for_cell is deterministic and yields identical streams across invocations.
• uniform_unit / uniform_int produce values inside the documented ranges.
