Module ptx_kernels 

GPU PTX kernels for graph algorithm operations.

Each kernel is emitted as a self-contained PTX module string, parameterised on SM version. PTX ISA is selected by SM: SM>=100 -> 8.7 (Blackwell), SM>=90 -> 8.4 (Hopper), SM>=80 -> 8.0 (Ampere), else -> 7.5 (Turing).

IMPORTANT: PTX kernel bodies use string concatenation (NOT format!()) for sections containing %rd, %r, %f, %fd register names, which Rust’s format macro would misinterpret as unused format arguments in edition 2024.
