Module semaphore 

N-permit gate — mirrors Effect.ts concurrency primitives backed by tokio::sync::Semaphore.

Use Semaphore::acquire with crate::resource::scope::Scope as the effect environment R so the permit is released when the scope is closed (via a Scope finalizer). Semaphore::try_acquire returns an owned Permit that releases on drop instead.
