- Replace the module-level writeMessage with a private DapClient.#writeMessage
that races sink.flush() against a 30 s cap and this.proc.exited, disposes the
client, and rethrows on either failure. A wedged adapter stdin previously
blocked writeMessage forever.
- sendRequest fires the write in the background and attaches a passive
promise.catch guard so the request timer's rejection cannot become an
unhandled promise before the caller's await subscribes. This also lets the
caller's timeoutMs win over a hung flush instead of waiting the full 30 s
write cap.
- #spawnSocketUnix and #spawnSocketClientAddr wrap the readiness / connect
race in try/catch that kills proc before rethrowing. Add a private
socketReadyTimeoutMs hook on DapSpawnOptions so tests do not have to wait
the full 10 s socket cap.
Regression tests cover all three failure modes: a wedged stdin flush must
reject sendRequest at the caller timeout with no unhandledRejection, and the
Unix + TCP client-addr spawn paths must terminate the detached adapter
process when the socket never appears.
