Function try_wcoj_triangle_u32_dispatch 

pub fn try_wcoj_triangle_u32_dispatch(
    rule: &Rule,
    inputs: &BTreeMap<String, CudaBuffer>,
    provider: &CudaKernelProvider,
    launch_stream: StreamId,
) -> Result<Option<CudaBuffer>>

Env-driven entry. Reads XLOG_USE_WCOJ_TRIANGLE_U32 and delegates to try_wcoj_triangle_u32_dispatch_with_gate.

Tests should prefer try_wcoj_triangle_u32_dispatch_with_gate to avoid races on the process-global env var; the env-driven form exists for production callers that want to opt in via configuration alone.
