Teleport landing visibility update

Teleport can no longer be used to vanish directly into grass with zero information for the opponent.

What changed:

• After a successful teleport, the landing position is briefly visible to the enemy script.
• This reveal still happens if the landing tile is grass.
• The goal is to prevent instant grass ambushes with no readable counterplay.

What did not change:

• Invalid teleport targets still fail and still consume cooldown.
• Teleport still cannot land directly on the current star tile.
• Teleport still applies the existing short fire lock when the landing tile is within Manhattan distance 4 of the enemy.
• Teleport cooldown is still 40 frames.

The Agent Guide and in-site battle manual have been updated to match this rule.
