Module seam_queue 

Bounded callback seams (spec 042, 3.12, I-3).

Every remote context and sink client declares an in-flight limit and a queue capacity, each 1 to 65,536 with no default. A call that finds the queue full is never enqueued: it is refused at once and counted. A call that waits for an in-flight slot waits no longer than its own deadline. A response that arrives after its caller stopped waiting is discarded and counted as late. Memory is bounded by the two limits, because every admitted call holds a slot until its exchange ends.
