WHAT'S NEW IN v1. 0. 3

- CUCoreLib hard dependency: migrated from soft dependency to hard dependency, removed Legacy mode and factory pattern

- KrokMP multiplayer compatibility:

- World generation (supply crates/corpses/airdrops) only runs on host, clients receive items via KrokMP sync

- Ammo/magazine unloading changed to world drop (FreshItemDrop) in multiplayer to prevent items going to host inventory

- Synced weapons/mags/ammo display correct custom sprites (template pre-creation calls ConfigureCustomItem)

- Inventory thumbnails show correct magazine/no-magazine state

- Console autocomplete fix: Command.argAutofill type corrected to Dictionary<int, List<string>>

- Red Rebel ice axe: cutting 12 / hammering 18 / backflip / cangetwet / tool

- 2 melee weapons: Red Rebel ice axe (climbing + cutting + hammering) and M-2 tactical sword (cutting + hammering), with backflip tag for vertical back display

- 9 custom ammo types with dedicated calibers

- 9 custom magazines with correct capacity and crafting recipes

- Caliber isolation system: three-layer Harmony patches prevent cross-caliber loading

- Weighted world spawns: 35% pistol / 20% SKS+shotgun / 17% SMG / 13% rifle / 10% sniper / 5% LMG

- Melee weapon drops: 13% chance in supply crates (40% ice axe / 60% M-2 sword)
