v0.11.2

Fixed

• Trigger input stream recovery: The trigger engine now automatically recovers
  from ALSA backend errors (e.g. POLLERR) by recreating the input stream, matching
  the existing recovery pattern used by the audio output stream. Previously, a single
  backend error would flood the logs with repeated error messages and leave the trigger
  engine non-functional.
• Trigger input thread priority: The trigger input callback thread is now promoted
  to real-time priority (SCHED_FIFO), matching the audio output and MIDI beat clock
  threads. This reduces scheduling jitter for trigger detection.
