feat(simulation): NpcBlueprint struct design, RON schema, and validator CLI (#611)

Define ZoneSpec, CultureProfile, and NpcBlueprint structs with serde/RON
deserialization. Ship example RON files as schema contract for the copy
team (#609, #610). Add validate-ron CLI for copy team to lint their files
without compiling the server.
