Every shipped module had an entry under "Included modules" except Slack,
which wasn't mentioned anywhere in the README — so the one module that can
send as the campus was also the one nobody could read about.
Its entry now sits with the others, in their shape: what it does, the tiles
it offers in the + picker (one transcript per configured channel plus the
two single send surfaces), its four admin groups and its tile settings —
all taken from modules/slack/module.json and client.js.
The testing paragraph listed the ProdCom, ProPresenter and PCO mocks but
not the Slack one, though CLAUDE.md has documented it all along; it is now
there with the SLACK_API_BASE line it needs.
