Replace Nebot plugin with Return YouTube Dislike

Removed the Nebot chat plugin and its files, and added the Return YouTube Dislike plugin with main process logic, renderer preload, and manifest. Updated plugin manager and main process to support internal plugin pages and improved plugin event handling. Minor updates to renderer and documentation.
