Node 22.13 minimum, and the library linked to its clone (closes #239)

`engines.node` and the README now state the minimum that quak's
`yarn.lock` needs: Node 22.13, or 23.5 on Node 23. `@inquirer/prompts`
and its packages refuse 23.0 to 23.4.

"Using the library" now links the clone with `yarn link` instead of
`yarn add file:../quak`. A linked quak runs on the dependencies the clone
installed from `yarn.lock`; `file:` resolved them afresh, so a new
upstream release could raise the Node minimum without any change here.
