Add directional shield toggle to AxeSwap

[LetMePractice]

Type of change

• Bug fix
• New feature

Description

Added a "Directional Shield" setting to AxeSwap. When enabled, the swap only triggers if the enemy is facing you. When disabled, it swaps regardless of direction.

Also added a "Shield FOV" setting to control the detection angle (default 60°). Uses dot product of normalized vectors with Math.cos(Math.toRadians(fov)) for accurate angle detection.

Note: if_blocking in scripting is unaffected and behaves the same as 1.3.7
