Fix headless class_name dependencies
- Replaced TeamData.Team type hints with int in all scripts - Added explicit preloads for headless mode class resolution - Created stub LagCompensation and DamageProcessor scripts - Fixed PluginManager, SpawnManager, EconomyManager, BuyZone, RoundManager, BuyMenuHandler, BombObjective class_name references - Updated server config to match ServerConfig.gd format Gray screen root cause: server scripts failed to parse in headless mode due to Godot 4 class_name loading order (Resource after Node), leaving server_main.gd non-functional — accepted connections but never spawned players.

## LagCompensation — Server-side lag compensation for hit-scan weapons.

##
|

## Records player positions per server tick into a ring buffer, then
|

## rewinds player positions to the tick when a shot occurred before

## performing the hit-scan raycast. This ensures that shots that would

## have connected at the time of firing (from the shooter's perspective)
|

## still connect even if the target moved before the server processed it.

##
|

## Architecture:
|

## LagCompensation (Node, add as child of GameServer)
|

## ├── record_tick(tick) — called each server tick BEFORE inputs
|
||||
## ├── rewind_and_raycast() — called by WeaponServer on fire
|
||||
## └── shot_processed signal — emitted after each compensated shot
|
||||
##
|
||||
## At 128Hz, the 128-entry buffer holds ≈1 second of position history,
|
||||
## which is more than enough for typical network RTTs (<200ms).
