Four generator spike improvements in one pass:
- #628: Fix name pool first-pick bias. build_name_pool now derives a
zone+culture-specific ChaCha20 RNG via FNV-1a mixing of (seed,
zone_type, culture_id), isolating name ordering from main RNG
consumption. Different zone types with the same seed now produce
different first names.
- #629: Behavior dedup within a zone run. build_behavior_pools
pre-shuffles each role's behavior list; gen_behaviors draws without
replacement. Falls back to random repeat with warning when pool
exhausts.
- #631: Relationship-to-behavior pipeline. Third generation pass
(~50% chance) replaces primary behavior with relationship-revealing
action — rivals talk past each other, friends drift together,
subordinates defer.
- #632: Want/State layer. NpcWant enum (Neutral/Bored/Alert/Suspicious/
AvoidingSomeone/LookingForInfo) biased by traits and role. Fourth
generation pass produces observable tells that leak internal state
through behavior. AvoidingSomeone resolves against negative-valence
relationships for named targets.
