MASSSIVE OPTIMIZATIONS/CHANGES TO CONVEYORS

 - Belt optimization enabled by default (mct_mixin.cfg) DISABLE IF HAVING ISSUES
 - Belts fully idle when no items/entites are on them after 2 seconds
 - Belts now stay visually active for 2 seconds when items/entites pass over them (even without redstone)
 - Massive reduction in duplicated code through clean inheritance hierarchy (easier updates & bug fixes)
 - All conveyor types now share consistent item handling (10-tick pickup delay + no-despawn logic)
 - Covered conveyors now have unified, reliable collision & selection boxes (horizontal + sloped)
 - Covered variants properly render walls and supports
 - Extractor arm now visually extends/retracts based on target block distance (up to 4 pixels)
 - Split conveyor now has reliable alternating output + redstone pulse toggle mode (SPLIT / ALL LEFT / ALL RIGHT)
 - Split redirection uses per-entity NBT for stable splitting behavior (no more lost items)
 - Drop conveyors improved insertion detection and trapdoor compatibility
 - Vertical conveyors now correctly render bottom belt/wall connections when appropriate
 - Vertical upward push logic refined for smoother entity movement and better centering
 - All covered variants (including vertical & extract) now visually connect properly to adjacent blocks
 - Consistent magnet suppression / reversion logic across all types prevents item glitches
 - Better redstone interaction on extractors (unpowered = active extraction)
 - Player sneaking now reliably stops movement on all conveyors
 - Improved model cache keys include dye, cover, direction, activity, and extension state
