One-shot emotes were routed by a hand-made class table that wrongly let `/pray` (75), the `/beg` family (79), and 126, 127, 131, 132 and 135 play upper-body. A mounted rider played every id on its upper body.
1.12.1 reads two byte tables:
- CLASS_A (`0x5fed90`): the ids that may play on the key bone.
- The mount set (`0x5fec80`): what goes to the mount model while mounted (`0x5fe7b5`..`0x5fe803`). Anything else plays nowhere.
What changed:
- Both tables now match the bytes, and a mount-set id is forwarded to the mount child.
- Unmounted `/eat` (61) always plays upper-body (`0x5fe834`).
- A model with no split bone arms nothing for an upper-body play (`0x5fdcc4`).
Tests pin both tables for every id 0..300, plus the mounted, eat and no-bone driver cases.
