Thx @JOTSR for the MR! I left a view comments.

deno publish --dry-run failed to resolve types imported in @cliffy/command/type.ts. Maybe I can use a temp patch if the bug persist and is not resolved before PR merge. (reported on @denoland/deno#22819)

[JOTSR]

Deno 1.41.3 was just released and fix denoland/deno#22819 so cliffy is now ready for jsr.
I made a last commit to run deno fmt and harmonize source code to continue from an fresh base.

There seems to be an issue with the snapshotTest method. The "deno run" command, which is called in the snapshotTest method, does not automatically load the deno config from the current working directory and does not resolve the imports correctly. It only works if I explicitly add the config to the command.

Thx again for your help @JOTSR! I think we can merge it now. I have add a workaround to get the tests working with the experimental workspace feature.
