Smoke run 3 showed inconsistent return strings — main-pm got
status='sent', be-pm got status='posted' for the same verb.
Confirmed say() already returns 'posted' at its sole success exit.
Added test_say_status.py to pin the canonical past-tense pattern
(note->'noted', say->'posted', notify_ack->'acked') and prevent
regression. dm() and notify() retain 'sent' — different verbs,
different semantics.
