Modify Assets/Scenes/Main Scene.unity: adjust multiple GameObject transforms and prefab instance localPositions (several large position shifts), rename/add objects (TeleporterE1, HallT_Label3 -> TeleporterE1, BulletInsert), add new prefab instance modifications, update mesh/material references and ray-tracing mode, remove many temporary/unused Cube entries to clean up the scene, and activate a character (Nolan). Update .idea workspace.xml: add changelist entry referencing the scene, add a short workItem entry timestamp, and remove a Unity reference flag. Overall: scene layout and prefab cleanup, plus small IDE metadata updates.
Move and consolidate many third-party plugin files and metadata from various locations (notably Assets/Third Parties/Plugins 1 and scattered Opsive/Photon folders) into a unified Assets/Plugins directory. Includes DOTween, PrimeTween, Native/BackroomsNoise, Sirenix/Odin Inspector, and Opsive UltimateCharacterController/shared libs, plus updates to several .meta files and removal of obsolete installer/legacy files. This standardizes plugin layout and cleans up duplicate/obsolete assets.
Add Unity .meta files for Assets/Plugins and Sirenix subfolders (Assemblies, NoEditor, NoEmitAndNoEditor, Demos). Commits folder metadata including GUIDs and folderAsset flags so Unity recognizes and preserves these plugin directories across machines and source control.
