Peterwolfs realistic tree felling

[1.1.7+1.21.11] - 2026-10-28

• Added 2 new realistic tree felling sounds (tree_fall_s1 and tree_fall_s2) with precise audio ground impact synchronization.
• Tree falling animation duration and acceleration are now mathematically synchronized with the sound: Profile 1 lands on tick 63 (3.15s) and Profile 2 lands on tick 126 (6.30s), aligning visual ground contact with the audio thud.
• Added visual triangular undercut (notch / klin podcinający) rendering on the trunk face while chopping with an axe, with dynamic 3D depth that deepens as chopping progresses.
• Dynamic multi-level trunk cut: felling at ground level (block 1) drops the entire tree leaving 0 blocks upright; felling at block 2 leaves a 1-block stump; felling at block 3 leaves a 2-block stump.
• Fixed fallen tree re-felling bug where an already felled tree or stump could be chopped again and appear to rise from the dead. Stumps and fallen logs are now strictly tracked and prevented from being detected as living standing trees.
• Greatly reduced and rebalanced fall damage: leaf damage reduced to 0.5 (quarter heart) and capped at 2.0 total (1 heart maximum), trunk damage scaled to config baseEntityDamage (6.0) with zero damage during initial slow lean (progress < 0.35), eliminating instant 1000 HP death when brushed by canopy branches.
• Added bee nest felling and physics integration: bee nests attached to trunks/branches fall with the tree and disturb bees upon impact.
