Armed Pillagers

Added

• ammoDropChance (0–100, default 50): percentage chance a gun-armed Pillager drops 1–3 of their ammo type on death. Set to 0 to disable, 100 to always drop.
• gunDropChance (0–100, default 5): percentage chance a gun-armed Pillager drops their gun on death. Defaults to rare so guns don't flood loot.
• Both settings now live in a new [drops] section in the config file.

Changed

• Pillagers that fail the spawnWithGunChance roll keep their crossbow and retain full vanilla drop behaviour (crossbow + arrows).
• The new drop logic only applies to gun-armed Pillagers.
• Clarified the spawnWithGunChance config comment to document the crossbow fallback behaviour.
