A merit node awards a configured achievement (awards_flag) to the player
the moment the playthrough arrives on it, with node provenance, then
presents a ceremony. Migration 028 extends node_type + the component_key
CHECK and adds awards_flag; the runtime grants the flag in advance/goto/
new-game write paths; MeritHost renders the ceremony (a component_key can
supply a bespoke one, e.g. a 3D model). Verified: teleport to a merit node
auto-grants its achievement.
