feat(mdz deploy): Make watch by default (Updated PR)

[tddschn]

Hi @gaocegege , I've been learning Go and now I think I have a much better understanding of the language, esp. how the module / package works.

Since the repo has been converted to public, I lost write access and here's a PR for #55 based on my fork.

[gaocegege]

Please rebase the upstream. Thanks!

[tddschn]

Should I base it off the 55-mdz-deploy-watch-by-default or the main branch?

To base it off main I think I'll have to open another PR.

To merge to upstream's 55-mdz-deploy-watch-by-default branch, you could try the Squash and Merge button on the GitHub UI. :)

[gaocegege]

Could you close the previous PR, then file a new one in the upstream?

[tddschn]

Of course. Please see #137 .
