Target Highlight

## 0.4.0
- Ranged mode: while you aim a bow, crossbow or trident (or a listed item), the highlight searches farther with a narrower cone.
- Activates while aiming (drawing, charging, or holding a loaded crossbow), with a short linger so it doesn't flicker. `trigger = HOLDING` makes it work whenever a ranged weapon is held.
- The ring and marker grow with distance so they stay readable at bow range (`scaleWithDistance`, `maxScale`).
- Draw progress: the ring fades up while you draw (`BRIGHTEN`) or switches colour at full draw (`COLOR`), controlled by `chargeBrightness`.
- `extraItems` lists extra items treated as ranged weapons, for example spell casters.
- Ranged items count as weapons for weapon-only mode.
