* fix(gateway): drain active turns before restart to prevent message loss
On SIGUSR1 restart, the gateway now waits up to 30s for in-flight agent
turns to complete before tearing down the server. This prevents buffered
messages from being dropped when config.patch or update triggers a restart
while agents are mid-turn.
Changes:
- command-queue.ts: add getActiveTaskCount() and waitForActiveTasks()
helpers to track and wait on active lane tasks
- run-loop.ts: on restart signal, drain active tasks before server.close()
with a 30s timeout; extend force-exit timer accordingly
- command-queue.test.ts: update imports for new exports
Fixes#13883
* fix(queue): snapshot active tasks for restart drain
