* feat: Register extensions in render process - Add CefExtensions type to hold V8 extension code - Pass extensions through BrowserProcessAppBuilder - Register extensions in RenderProcessHandler on WebKit initialization - Decode JSON extensions from command line switch - Prefix extension names with "v8/" per CEF convention - Include actual JSON in error messages for debugging l * feat: refactor window.cef API and register as CEF extension * fix: remove debug print statements in render process handler * refactor: centralize EXTENSIONS_SWITCH constant in util.rs * fmt * refactor: implement Default trait for CefApiHandler * docs: add documentation for CefApiHandler and its JavaScript API functions --------- Co-authored-by: not-elm <elmgameinfo@gmail.com>
