feat(markdown): start the preview server from F2 when it's down
cj/markdown-preview now brings up the simple-httpd listener itself instead of signaling a user-error pointing at cj/markdown-preview-server-start. The two-command flow guarded against a surprise network listener, but the preview is the only reason the listener exists, so the guard was just an extra step. I kept the start command for manual use.
