Fix all Clippy warnings across the server codebase (2411 insertions, 1341
deletions). Raise type-complexity-threshold to 750 and too-many-arguments
to 12 in .clippy.toml for idiomatic Bevy ECS system signatures. The server
now passes `cargo clippy -- --deny warnings` cleanly.

ToleranceBreachEvent emitted when NPC stress exceeds per-seed threshold.
ToleranceBreached marker prevents duplicate events per episode, cleared
on recovery. check_tolerance_threshold system runs after update_mood,
integrates with mood FSM to push toward Hostile/Anxious. Background-tier
NPCs excluded. Unblocks #250 (triangle escalation).
