vscode: enable defining mcp.json separate from settings.json (#7441)
VS Code 1.102 separates MCP configuration from `settings.json` to a profile-specific `mcp.json`. VS Code automatically performs this separation if MCP configuration is detected inside `settings.json` which conflicts with the immutability of the settings.json that home-manager supplies.
