Subject: [PATCH] fix: Rider config path and add MCP registry manifest (#604)

- Fix RiderConfigurator to use correct GitHub Copilot config path:
  - Windows: %LOCALAPPDATA%\github-copilot\intellij\mcp.json
  - macOS: ~/Library/Application Support/github-copilot/intellij/mcp.json
  - Linux: ~/.config/github-copilot/intellij/mcp.json
- Add mcp.json for GitHub MCP Registry support:
  - Enables users to install via coplaydev/unity-mcp
  - Uses uvx with mcpforunityserver from PyPI
