Two bugs that prevented turn-manager dormancy from ever triggering:
1. isEmptyTurn too strict: agents output multi-line text ending with
"NO_REPLY" on the last line, but the regex ^NO_REPLY$ required the
entire string to match. Now checks only the last non-empty line.
2. blocked_pending counter inflation: non-speaker suppressions incremented
the counter but their stale NO_REPLYs were discarded at the
!isCurrentSpeaker early return without decrementing. Over a full cycle
the counter inflated by the number of suppressions, causing the agent's
real empty turn to be misidentified as stale when it finally arrived.
Fix: at both early-return points in agent_end (!isCurrentSpeaker and
!isTurnPending), drain blocked_pending when the turn is empty.
Also fixed: pollForTailMatch now uses any-message detection (instead of
tail-fingerprint content matching) with a 30 s timeout, avoiding infinite
polling when agents send concise Discord messages after verbose LLM output.
