- guard null new/old holder in endAnimations() change loops to fix NPE
- remove changeInfo from list inside endAnimations() so isRunning() reports false after teardown
- clear me_chan_texas_item_anim_tag on natural end of remove/move, matching add path
- drop dead sDefaultInterpolator field
- expose DefaultItemAnimator as public so apps can drive it directly
- add ItemAnimatorDemoActivity covering add/remove/move/change (with and without payload) and cancellation paths
- document trigger logic in doc/arch/item-animator.md
