Add authorable per-level briefing checklist

The case briefing showed a wall of body text. Add a checklist of short,
player-tickable steps authored per level: a new `checklist` on the level brief
(table osint.level_brief_checklist_items), read/written with the board, cloned
on template freeze/instantiate, and carried through the mystery importer and the
mystery:pull exporter. Player tick state is guidance-only, persisted locally per
level rather than on the shared board. Convert the Barricelli inventor-proof
brief from prose into a short intro plus a six-step checklist.
