New Mining Shapes

• Added the Shaft shape for digging vertically toward bedrock
• Shaft width can be adjusted by sneaking and scrolling
• Shafts can continue through air gaps
• Added the Staircase shape
• Staircase width can be adjusted by sneaking and scrolling.
• Staircases can contain up to 32 steps
• Staircases travel upward when looking at the top half of a block and downward when looking at the bottom half

Shaft Config

Added a configurable liquid policy for shafts:

• Stop at all liquids
• Skip water
• Skip all liquids

This allows shafts to continue past flowing water without unintentionally passing through lava unless configured to do so.

Configuration Improvements

• Redesigned the Mod Menu configuration to be inline
• Moved option descriptions into hover tooltips
• Added the shaft liquid behavior setting
• Removed the redundant Food Exhaustion toggle
• Food exhaustion can now be disabled by setting its scale to 0.0

Preview Improvements

• Tunnel and Staircase outlines can now be seen through blocks
• Through-wall rendering is limited to those structured shapes to prevent the severe performance loss caused by rendering thousands of visible outline edges
• Vein, Leveler, and Shaft previews retain faster depth-tested rendering
