Create shield wall effect

Description

Note: Avoid using shaders for this until later. For now use. a stretcheable gradient between pucks with a collider

Acceptance Criteria

• An adjustable gradient shield wall exists.
• Shield wall uses two linked pucks to generate border
• Shield wall linkages are based on calculating the outermost border

Implementation

• Create Shield wall controller referecing all child shield pucks
• Add logic to calculate the linked path based on given children
• add shield wall shader effect
• Add collider between shield pucks
