fix(system_prompts): resolve nested local command groups in CLI docs generator

The CLI docs generator anchored on the first `new Command()` in a file and
never resolved locally-defined command groups passed as
`.command("name", localCmd)`. For datatable this flattened the nested
`migrate` group: it emitted `datatable new/up/down` plus a bare
`datatable migrate`, and mislabeled the datatable command with the migrate
group's description. jobs was broken the same way (its description was pull's,
and pull/push rendered empty).

Anchor block extraction on the `export default`ed command, recurse into
locally-defined `const x = new Command()` groups mounted as subcommands, and
render nested sub-subcommands. Regenerated docs now show
`datatable migrate new/up/down` and `jobs pull/push` with their real
options.
