Additional integration tests for conversation cooldown application, distance
termination with both NPCs receiving cooldown, and edge cases in the NPC-to-NPC
conversation pipeline.

update_relationship_dynamics runs once per game-minute (10 ticks). Edges
inactive for 1+ game-hours (600 ticks) decay trust 1 point toward 0 per
minute. Creates social texture: NPCs who haven't interacted drift to neutral
without active maintenance. Blocks #249 (social propagation, Sprint 15).
Constants: DECAY_INTERVAL_TICKS=10, DECAY_INACTIVITY_THRESHOLD_TICKS=600,
DECAY_DELTA=1. Integer arithmetic only (D-010 determinism).

ActivityState component tracks the activity an NPC is currently performing
at their routine destination (activity name, phase, started_tick). The
enter_activity system runs after movement validation and sets ActivityState
when an NPC has arrived with no active path. Cleared on phase transitions.
Feeds TellTrigger::DuringActivity and D-028 Layer 2 situation matching.
Unit tests verified via shift_change room integration.

InteractionMemory component tracks interaction_count, last_interaction_tick,
and notable_events per NPC. Drives D-028 Layer 2 situation activation:
first_meeting (count==0) and repeated_visit (count>=3). warm_active in mood
system now derives from InteractionMemory within a 300-tick window.
Trust progression wired into dialogue systems: talk completion (+1),
walk-away (-1), confrontation (-2) emit TrustEvents consumed by update_trust.
InteractionEvent (WalkAway, Confrontation) recorded in notable_events for
fast per-pair access.
Adds FirstMeeting and RepeatedVisit Situation variants. 18 unit tests in
interaction.rs. All arithmetic integer-only (D-010 determinism). No HashMap.

Adds test_world::invariants with 29 world-query invariants (structural,
perception, population, simulation) and 7 system-execution tests. All
invariants are gated behind the gauntlet feature and run against the
fully-initialized gauntlet world. Documents StableId ranges through
Sprint 14 rooms.

8-state NPC mood FSM driven by stress, time of day, and interaction events.
Adds MoodState component, derive_mood() pure function, and update_mood() Bevy
system wired into NpcPlugin. Adds Focused as 9th Mood content tag (D-035
Sprint 8 amendment). Syncs CurrentMood for Layer 4 dialogue selection.
31 unit tests covering priority ordering, boundary conditions, and system
integration. All random values route through SimRng (D-010 determinism).
No floats. No HashMap.

Implements server-authoritative per-word occlusion for NPC conversations.
ConversationEventBuffer drains into ObserverSnapshot each tick so the client
receives only words audible from the player's position. Updates test fixtures
to include the new conversation_events and conversation_ended fields.
