zatopiony69-prog/TowerSentinel ? reverse-engineered prompt

Build me an EXILED plugin for SCP Secret Laboratory that automatically places and controls a defensive tower around the Surface admin tower when a valid player is nearby.

I want it to feel like a real in game defense system, with animated barricades and a turret that fights back when someone shoots it or throws grenades at it. Ordinary attacks should trigger a minigun style response, stronger weapons should trigger a heavier laser style response, and grenade attacks should be thrown back from a cannon. Make sure the tower only reacts to the actual attacker, not everyone nearby, and that walls, doors, glass, and players can block retaliation properly.

Please make the placement and damage settings configurable, include optional hit messages for players, and clean everything up correctly at round end or when the plugin is disabled. Keep it safe and self contained, with no external network calls or telemetry. If you need to look up current EXILED docs online, go ahead.
