## Fixed

### Ability activation spam on right-click

- **Symptom:** Every right-click showed *"You need Level 5 to use Whirlwind!"* (often twice), even when eating, opening chests, or interacting with blocks.

- **Root cause:** The first class ability (e.g. Whirlwind) is auto-unlocked at character creation but requires a higher character level to use. Ability checks ran on almost every right-click — on NeoForge via `RightClickItem`, which fires for all item interactions.

- **Fix (Paper & NeoForge):**

  - Abilities only activate on **right-click into open air** with the **main hand** (NeoForge: dedicated `AbilityListener` with raycast miss check).

  - Auto-selected abilities below the required character level are no longer treated as the active ability.

  - Level requirement messages are shown only when the player **manually selected** that ability in the abilities GUI.

  - Off-hand interactions no longer trigger duplicate ability checks.
