Hostile Tactics

# Hostile Tactics v0.7.0: Warband

- Added local coordination between zombies, skeletons, and creepers.
- Mobs can now share short-lived combat signals using fair sight, last seen, and last heard information.
- Zombies apply front pressure, skeletons look for better crossfire angles, and creepers are more likely to seek side or rear approaches.
- Added Threat Dial scaling for Warband behavior.
- No damage, health, spawn, fuse speed, or explosion strength buffs.
- No wall tracking or global hive-mind behavior.
- Improved debug/status output for active Warband signals.
