Adds Verb variants: auth, vcs, chat, search, storage, media, mon, vault, people, docs, meet, drive, mail, cal, find. Each delegates to the corresponding SDK cli.rs dispatch function. Removes the legacy `user` command (replaced by `auth identity`). Renames Get's -o to --kubectl-output to avoid conflict with the new global -o/--output flag. Enables all SDK features in binary.
