Darwinism

New Biological Adaptations

• The "Survival Instinct" (Haste): Using a tool or swinging your arm while facing a block (within 4 blocks) now triggers Haste II, allowing for rapid-fire excavation.
• Emergency Stabilization: When health drops below 1 heart (2 HP), the serum enters an "overdrive" state, granting Resistance V (total invulnerability) and Regen V for 10 seconds.
• Adrenaline Recovery: Reaching low health (below 3.5 hearts) now triggers a steady Regeneration II pulse.
• Unstable Metabolism: When starving (below 1 shank), the serum has a 5% chance per tick to jumpstart your hunger with Saturation.

Logic & Balance Tweaks

• Optic Sensitivity: Refined Night Vision to trigger only in near-total darkness (light level < 2).
• Precision Mining: Scaled the mining detection raytrace to 4 blocks to perfectly match Survival reach.
• Movement Stability: Optimized the Speed II sprint timer (3-second charge-up) to utilize persistent global variables for better performance.
