//! Runtime gate for the `Some(0)` concurrency footgun: a stored `concurrent_limit <= 0`
//! must read as "disabled", never as a zero-slot cap that permanently blocks the job at the
//! concurrency gate (the re-queue storm the zombie monitor eventually fails as a fake OOM).
//!
//! Run with:
//!   cargo test -p windmill-queue --test concurrency_limit_zero_test
