v1.0.9

Fixed

• Stop replying into conversations a human teammate is handling. On a shared
  team queue (e.g. Socials, once WhatsApp went live), a reopened conversation
  drops back to admin=0, so the unassigned poll let Sisi barge into a thread a
  human was actively working (observed live: ~20 collisions in 30 min). Now, if
  any human teammate has replied in a conversation, Sisi takes no further turn in
  it at all -- not just skipping messages before their last reply. She only
  handles conversations with no human turn (genuinely fresh, or bot-only). (#40)
