🧰 Changes

outstanding tasks:

• command
• tests
• optional --action arg? edit: might be a good enhancement further down the line, but going to pass on this for now!
• tests for useSpecVersion
• test for pending timeout (there's a nock API for duplicating an interceptor, use that!)
• finalize command docs

ideas for future enhancements

• optional --action arg for use in CI to prevent accidental overwrites
• optional --timeout arg to allow user to configure timeout
• add new test project to sync to in CI (i.e., adding back what i removed in d69d1aa)
• GHA onboarding support
