acceptPump
Persistent, concurrent, handshake-timed accept loop. Drains source forever; each accepted Connection is handled in its OWN child coroutine under handshakeTimeout, so one conn that connects but never completes its handshake can never starve later conns — the sequential while (isActive) { handle(source.accept()) } pattern wedges on such a conn; this replaces it.
On success the conn is left live (owned by handle — e.g. now published into a mesh). On handle failure or a handshake timeout, onFailure is invoked and the conn is closed. kuilt-core is logger-free, so onFailure is how a host surfaces a per-link rejection/timeout to its own logger.
Return
the pump Job (a child of the receiver scope); cancel it to stop accepting.
Parameters
the accept source drained forever until the pump Job is cancelled.
the ceiling on a single conn's handle; a conn whose handling exceeds it is abandoned (its child coroutine cancelled) and closed, and onFailure sees a HandshakeTimeoutException.
invoked with the failure whenever a conn's handle throws or times out. Best-effort, non-suspending; defaults to a silent absorb.
handles one accepted conn to completion (the handshake + publication). Runs in its own child coroutine under handshakeTimeout.
