Tool catalogue
tool-catalog lists what each command does, whether it uses the network, writes files or costs money.

Pick a command
Run seohead --help or search with tool-catalog. Each command has one job and a single entry in the catalog.
Read JSON and the exit code
Output is always JSON on stdout. Exit code 0 means the command completed. Exit code 1 means it could not finish, and the reason is in the JSON.
