fix(Predator): add bulletSpawnDistance for concentric bullet spawn

[sandbushman]

Changes

Problem: Predator's 3 barrels have different visual sizes (110, 95, 80), and bullet spawn position was computed from barrel.physicsData.values.size. This caused the small bullet to spawn ahead of the mid bullet, which spawned ahead of the big bullet — all at different distances from tank center. In diep.io all 3 spawn concentrically.

Fix: Added optional bulletSpawnDistance field to BarrelDefinition. When set, it overrides the barrel's visual size for bullet spawn distance calculation. Set to 110 on all 3 Predator barrels so they all spawn at the same radius.

Bonus fix: The barrel.distance field in Bullet.ts was not being multiplied by scaleFactor, inconsistent with Barrel.ts. Fixed.

Files changed

File	Change
src/Const/TankDefinitions.ts	Added bulletSpawnDistance?: number to BarrelDefinition interface
src/Entity/Tank/Projectile/Bullet.ts	Uses (bulletSpawnDistance ?? size) * scaleFactor for spawn position + fix distance scaling
src/Const/TankDefinitions.json	Added bulletSpawnDistance: 110 to all 3 Predator barrels

No regression risk: bulletSpawnDistance is optional — defaults to size for all other tanks.

This is probably not the right way to do this - Bullet spawn logic needs to be reworked eventually
