CobblemonBahaviours

Problem: Aggressive Pokémon attacked instantly when in range, not giving Cobblemon's defense system time to let the player's Pokémon protect the trainer.

Fix: Added a configurable first-attack delay. When an aggressive Pokémon spots a player:

1. Approach phase (default 60 ticks = 3 seconds): Pokémon approaches slowly (half speed) but does not attack
2. After the delay, normal attack behavior begins
3. Delay resets if the target changes
