Upshift

Added

• Distant mob AI throttling on the integrated server. A mob farther than the configured distance from every player skips its sensing tick and only runs the cheap running-goal pass on most ticks; its full goal scan happens once per interval. Navigation, movement, look and jump control still run every tick, so distant mobs keep moving.
• Throttle distant mob AI, AI distance (48 blocks) and AI update rate (every 4 ticks) options on the Optimizations page. Mobs within range of any player are never throttled.

Safety

• Persistent mobs, named mobs, passengers, vehicles, the Ender Dragon and the Wither are excluded, so farms, pets and bosses are unaffected.
• The phase gate lines up with the tick vanilla already reserves for a full goal update, so an even interval always lands on a full tick.
• The decision is made once per game tick and cached on the mob; the distance test uses the level's player list and primitive math, with no Vec3 allocation.
• A dedicated server never sees the mixin: Upshift is a client mod and the throttle lives in the integrated server only.

Technical

• MobAiThrottleMixin wraps Sensing.tick and GoalSelector.tick in Mob.serverAiStep with @WrapOperation; there is no @Overwrite.
• Config schema 7; existing configs migrate automatically.
• Java 21 bytecode.
