[FEATURE] Custom Tool Fix and Add inspection window for all the tools (#414)

* Update .Bat file and Bug fix on ManageScript

* Update the .Bat file to include runtime folder
* Fix the inconsistent EditorPrefs variable so the GUI change on Script Validation could cause real change.

* Further changes

String to Int for consistency

* [Custom Tool] Roslyn Runtime Compilation

Allows users to generate/compile codes during Playmode

* Fix based on CR

* Create claude_skill_unity.zip

Upload the unity_claude_skill that can be uploaded to Claude for a combo of unity-mcp-skill.

* Update for Custom_Tool Fix and Detection

1. Fix Original Roslyn Compilation Custom Tool to fit the V8 standard
2. Add a new panel in the GUI to see and toggle/untoggle the tools. The toggle feature will be implemented in the future, right now its implemented here to discuss with the team if this is a good feature to add;
3. Add few missing summary in certain tools

* Revert "Update for Custom_Tool Fix and Detection"

This reverts commit ae8cfe5e256c70ac4a16c79d50341a39cbac18ba.

* Update README.md

* Reapply "Update for Custom_Tool Fix and Detection"

This reverts commit f423c2f25e9ccff4f3b89d1d360ee9cf13143733.

* Update ManageScript.cs

Fix the layout problem of manage_script in the panel

* Update

To comply with the current server setting

* Update on Batch

Tested object generation/modification with batch and it works perfectly! We should push and let users test for a while and see

PS: I tried both VS Copilot and Claude Desktop. Claude Desktop works but VS Copilot does not due to the nested structure of batch. Will look into it more.

* Revert "Merge pull request #1 from Scriptwonder/batching"

This reverts commit 55ee76810be161d414e1f5f5abaa5ee30ddd0052, reversing
changes made to ae2eedd7fb2c6a66ff008bacac481aefb1b0d176.
