The reports desk: a slip for surprises, replies in the hall

Browse Source 
A Report button in a room's masthead files what happened and what was
expected, with a screenshot if there is one, pinned to the room and the
turn and rung through Sentry. Reports and the keeper's replies live in
feedback.jsonl beside the ledgers; the hall shows each seat's reports
with the thread under them and a line to answer. pull-reports.sh mirrors
the desk locally, report-reply.sh answers, and a skill works the desk.
