New /output-style slash command lists or switches output styles, currently hidden behind internal checks

Output styles change how Claude Code's responses are formatted or presented; this command would give a direct way to see or switch between them from the command line, but since it is gated behind internal checks, most users won't see it yet.

Added since A small documentation edit on Modifying system prompts touched a line naming /output-style after this was published. * **CLI**: run `/output-style <style>`, for example `/output-style concise`, or run `/config` and select one.
