The interrupt mechanism for regular text messages (non-commands) during
active agent runs relied on a single async polling task
(monitor_for_interrupt) with no error handling. If this task died
silently due to an unhandled exception, stale adapter reference after
reconnect, or any other failure, user messages sent during agent
execution would be queued but never trigger an actual interrupt — the
agent would continue running until it finished naturally, then process
the queued message.
Three improvements:
1. Error handling in monitor_for_interrupt(): wrap the polling body in
try/except so transient errors are logged and retried instead of
silently killing the task.
2. Fresh adapter reference on each poll iteration: re-resolve
self.adapters.get(source.platform) every 200ms instead of capturing
the adapter once at task creation time. This prevents stale
references after adapter reconnects.
3. Backup interrupt check in the inactivity poll loop: both the
unlimited and timeout-enabled paths now check for pending interrupts
every 5 seconds (the existing poll interval). Uses a shared
_interrupt_detected asyncio.Event to avoid double-firing when the
primary monitor already handled the interrupt. Logs at INFO level
with monitor task state for debugging.
