Drop the coop_dungeon system per migration plan §5. 11 coop_*.go files
removed; cleanup_l3.go added with an idempotent per-run status-guarded
UPDATE that cancels any open/active runs and refunds member contributions
plus unsettled bets via EuroPlugin.Credit. Tables retained for now;
schema purge deferred to a future GOGOBEE_COOP_PURGE pass.
adventure.go drops !coop dispatch, coopTicker, the startup combat-lock
hook, and the !coop help line. adventure_scheduler.go loses the
activeCoopMemberSet skip branch and the post-reset combat-lock call.
adventure_render.go drops the teaser plus the in-coop status block;
replaced with a one-week morning-DM closure announcement
(TODO: remove after 2026-05-16). TestPickCoopTeaserCandidate_SkipsLeader
removed.
go vet ./... and go test ./... clean.
