Final G9 step. The schema no longer creates current_room or room_seq_json on fresh installs, and existing prod schemas drop them via purgeLegacyZoneRunColumns() once the operator flips GOGOBEE_BRANCHING_PURGE=1. - CREATE TABLE dnd_zone_run loses both columns; comment updated to point at G1's columnMigrations for the graph-mode columns. - cleanup_g9.go mirrors the L5 idempotent-purge shape: ALTER TABLE DROP COLUMN per legacy column, "no such column" treated as already done, default-off. - Wired into adventure Init alongside purgeLegacyAdvCharacterTable. - Plan doc marks G9 complete.
