Slabbed

Slabbed 0.4.2-beta.1 for Minecraft 1.21.1

This beta rebuilds the 1.21.1 line with the latest Slabbed support fixes and release-jar cleanup.

Fixed

• Fixed the severe lag spike caused by repeated missing diagnostic-class lookups during rendering.
• Fixed chain visual/selection alignment so lowered chain setups keep model, outline, and targeting in sync.
• Fixed pointed dripstone combine behavior on lowered Slabbed targets.
• Fixed Terrain Slabs compatibility for placed bottom slabs:
  • full blocks can stack flush without gaps
  • floor-standing objects now sit flush on supported Terrain Slab bottom slabs
  • genuine hanging objects and ceiling chain geometry remain unchanged
• Fixed object placement on flat Terrain Slab bottom surfaces.

Improved

• Added better /slabdy diagnostics for testing lowered-state source, dy, target half, and supporting block state.
• Cleaned the packaged release jar so proof/debug/test helpers do not ship in the runtime artifact.

Notes

• Terrain Slabs generated/self-rendering quirks remain Terrain Slabs-side behavior where Slabbed reports dy=0.
• This is a beta release; please report any weird placement, targeting, or visual alignment issues with screenshots and the block setup.
