Instantiating material due to calling `renderer.material` during edit mode

[Olney1]

When running the MCPForUnity editor tooling, the following warning is logged by Unity:

Instantiating material due to calling renderer.material during edit mode. This will leak materials into the scene. You most likely want to use renderer.sharedMaterial instead. System.Reflection.PropertyInfo:GetValue (object) MCPForUnity.Editor.Helpers.GameObjectSerializer:GetComponentData (UnityEngine.Component,bool) (at ./Library/PackageCache/com.coplaydev.unity-mcp@c7cf9cd32067/Editor/Helpers/GameObjectSerializer.cs:359) MCPForUnity.Editor.Tools.ManageGameObject:GetComponentsFromTarget (string,string,bool) (at ./Library/PackageCache/com.coplaydev.unity-mcp@c7cf9cd32067/Editor/Tools/ManageGameObject.cs:971) MCPForUnity.Editor.Tools.ManageGameObject:HandleCommand (Newtonsoft.Json.Linq.JObject) (at ./Library/PackageCache/com.coplaydev.unity-mcp@c7cf9cd32067/Editor/Tools/ManageGameObject.cs:157) MCPForUnity.Editor.MCPForUnityBridge:ExecuteCommand (MCPForUnity.Editor.Models.Command) (at ./Library/PackageCache/com.coplaydev.unity-mcp@c7cf9cd32067/Editor/MCPForUnityBridge.cs:1053) MCPForUnity.Editor.MCPForUnityBridge:ProcessCommands () (at ./Library/PackageCache/com.coplaydev.unity-mcp@c7cf9cd32067/Editor/MCPForUnityBridge.cs:894) UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

Expected behaviour

Editor tooling should use renderer.sharedMaterial when inspecting or serialising component data during edit mode, to avoid instantiating materials and leaking them into the scene.

Actual behaviour

The code path in GameObjectSerializer.GetComponentData calls renderer.material in edit mode, which causes Unity to create unique material instances and logs warnings.

Steps to reproduce

1. Open Unity editor with MCPForUnity installed
2. Trigger any action that runs ManageGameObject.GetComponentsFromTarget in edit mode
3. Observe console warnings about renderer.material instantiation

Suggested fix

Update editor-side reflection/serialization code to use renderer.sharedMaterial when accessing Material properties during edit mode.

I should be able to look at it next week, but if anyone else has capacity please go ahead
