GestureArenaManager class

Manages gesture arenas for conflict resolution.

When multiple recognizers compete for the same pointer sequence, the arena resolves which one wins. The first recognizer to claim acceptance wins; all others are rejected.

Each arena is identified by an integer key (typically derived from a pointer ID or a monotonic counter).
