Add test for queries with visibility checks

Adds a baseRange parameter to parabolic queries providing simple
2D detection alongside parabolic detection.
StandGround and Chase stances now use full attack parabolic range
with vision range as baseRange, allowing units to attack enemies
visible through friendly vision.
