IG: Item Clumps

[1.0.21+26.2] - 2026-07-15

Fixed

• Fixed compatibility mismatch with Magnet mod version 26.2. The reflection helper now queries for the new ig_magnet$isMagnetized method signature first, falling back to the 26.1 ig$isMagnetized signature, preventing items from clumping while in magnet flight.
• Fixed properties synchronization during partial merges. The target item entity now inherits pickupDelay and age from the merged entity, preventing items from bypassing pickup delays or despawning prematurely.
