CLI Missing 'hand config' command mentioned in documentation

[Abhishek21k]

The documentation at https://www.openfang.sh/docs/hands mentions the command:

openfang hand config browser --set headless=true

However, this command does not exist in the current CLI. Running openfang hand --help shows the following subcommands:

  list          List all available hands
  active        Show currently active hand instances
  install       Install a hand from a local directory containing HAND.toml
  activate      Activate a hand by ID
  deactivate    Deactivate an active hand instance
  info          Show detailed info about a hand
  check-deps    Check dependency status for a hand
  install-deps  Install missing dependencies for a hand
  pause         Pause a running hand instance
  resume        Resume a paused hand instance

Either the config subcommand should be implemented for hands, or the documentation should be updated to reflect the correct command (possibly openfang config set hand.browser.headless true if that's the intended alternative).
