Access and control a running GNU Emacs instance via `emacsclient`. Use when an agent needs to inspect Emacs state, evaluate Elisp, visit files or locations, or trigger editor-side actions inside the user's live Emacs session instead of only editing files on disk. On Windows, run `emacsclient` from PowerShell so the PowerShell function can resolve Emacs correctly. On Linux, run `emacsclient` from the default shell via `PATH`.
