Function try_wcoj_triangle_u32_dispatch_with_gate 

pub fn try_wcoj_triangle_u32_dispatch_with_gate(
    gate_enabled: bool,
    rule: &Rule,
    inputs: &BTreeMap<String, CudaBuffer>,
    provider: &CudaKernelProvider,
    launch_stream: StreamId,
) -> Result<Option<CudaBuffer>>

Test-friendly form that takes the gate as an explicit boolean. Production callers use try_wcoj_triangle_u32_dispatch which reads the env var.
