## WeaponRegistry — central registry of all weapon definitions.
##
## All weapon data is defined here as static constants. Systems that need
## weapon stats (WeaponManager, BuyMenu, RoundManager) reference this.
##
## To add a new weapon: create a WeaponData resource in client/weapons/data/
## and register it in the ALL array below.
