-- Empyrion EAH-style features. Three tables:
--
-- 1. empyrion_events — append-only log of unsolicited Event_* packages
--    streamed from the bridge. Powers the player-history view, chat log,
--    and the "what happened while I was away" overview.
--
-- 2. empyrion_inv_templates — operator-defined inventory kits (name +
--    JSON list of {itemId, count}). Click "Apply" on a player row to
--    drop the whole kit via Request_Player_AddItem fan-out.
--
-- 3. empyrion_known_players — projected from empyrion_events. Cached
--    last-seen / first-seen / login count for the players-list view so
--    we don't aggregate the events table on every refresh.
--
-- All tables are scoped by instance_id so two running empyrion instances
-- on the same agent (rare but allowed) keep separate state.
