[cli] detatch the CLI into jsr:@netzo/cli

[miguelrk]

jsr:@deno/deployctl has received recent updates and it would be a good time to re-fork the upstream CLI and adapt it for Netzo (only what is relevant), as well as detach it to a standalone package published to JSR. The rest of the library can be kept in deno.land/x since JSR does not allow importing dependencies via https imports, which is currently required to alias react dependencies like radix-ui, cmdk, etc. Once compatibility is improved for react, we could migrate the https imports to npm: imports and migrate the library as well.
