Mine Piece: New Era 1.67.0 (Forge 1.20.1)

- Gear Five Giant Grab Slam now spins the grabbing arm for exactly three seconds before throwing the enemy into the ground.
- The arm completes 15 full rotations (five per second) while holding one enemy.
- Both Elbaph and Onigashima Luffy use the updated sequence.
- The held enemy follows the same timed palm on the server and client, preventing network interpolation from separating them from the fast-moving arm.
- The final hit remains tuned toward 40 health against Four Emperors Shanks, with one terrain-only crater explosion.
- Luffy still grows fivefold, returns to normal size and then waits through a 15-second cooldown.
- Earlier combat and model fixes are retained.

Validation: compiled for native Forge/Minecraft and MinePiece 14/15 bindings; controller, packet-lag correction, damage/cooldown and previous combat tests; actual GeckoLib bone-to-hand transforms for both rigs; headless OpenGL animated preview.
No live Minecraft client playtest was performed.
