Improve AI: bed memory (30-block search), relationship-based follow goal, crouch fixes

- EllieSleepGoal: check stored bedPos first, search 30 blocks on miss
- releaseBed() no longer clears memory; forgetBed() for destruction
- New FollowPlayerGoal: 50-75% distant follow, 75-99% closer, 100% approach
- fix: crouch animation thenLoop, idle doesn't override crouching
- fix: sleep Y rotation = facing.toYRot() (head toward headboard)
- fix: checkLowCeiling scan range reduced (2-4 blocks, 3 for path)
