Fix AI: simplify crouching, rewrite EllieSleepGoal, clean up idle anim

- checkLowCeiling: only check current position (no path/node scanning)
- Crouch height: 1.0 (fits in 1-block gaps without suffocation)
- EllieSleepGoal: remove hurtTime from canUse, simplify canContinueToUse
- IdleAnimationGoal: no longer stops navigation on start
- Also: register FollowPlayerGoal, bed memory improvements
