Aimbot v2: bone checklist and numeric smoothness

- Aimbot -> Bones: Head, Torso (chest+stomach), Left/Right arm,
  Left/Right leg; the aimbot aims at the nearest selected hitbox point on
  the chosen target (head uses the head hitbox/bone fallback)
- Aimbot -> Smoothness: value 1..45 deg/tick, Left/Right in the menu to
  adjust, persisted as smooth=N; default 5 (previous behaviour)
- config: bone_* toggles + smooth under [aimbot]
- menu gains a NODE_VALUE type (right-aligned value, Left/Right edit)
