Make `zli config` and config subcommands show usage/help when invoked with
missing required args, instead of Cobra’s generic “accepts N arg(s)” errors.
Example:
- before: `zli config add` -> `Error: accepts 2 arg(s), received 0`
- after: `zli config add` prints `zli config add <config-name> <url>` usage/help1~fix(zli config): print help for missing args
