Previously dispatchToClaude awaited child.on(close) before yielding the done
event. Claude CLIs Bash tool occasionally leaves ssh/bash grandchildren alive
(e.g. a GUI app that ignores SIGPIPE on the remote end of a piped ssh command);
that kept claude -p alive past end-of-turn, which kept the bridge SSE stream
open, which kept OpenClaw from committing the turn to its session jsonl.
Switch to emitting done as soon as the terminal result stream-json event
arrives. Spawn claude in its own process group (detached:true) and schedule
a best-effort SIGTERM/SIGKILL sweep of leaked descendants; temp-file cleanup
runs asynchronously on actual process close.
