chore: Add a pre-built dev environment

[v6]

Addresses #511

If you install Virtualbox and Vagrant, you can run vagrant up in the root of the repo and get a temporary environment with the resume-cli, NVM, NPM, and node pre-installed and ready to try out!

@v6 thanks for putting together a pre-built dev environment — lowering the barrier to contributing was a good goal. The monorepo's toolchain (pnpm + Turborepo) replaced this era's setup entirely, but the spirit of "make it easy to hack on" carried forward.

Here's the context: JSON Resume is under active maintenance again (2026), and resume-cli has been revived — but the codebase moved into the jsonresume.org monorepo at packages/cli (merged in jsonresume/jsonresume.org#278). This standalone repo is being archived with a redirect, so PRs against it can no longer land — which is why I'm closing this rather than merging it.

If the change still matters to you, we'd genuinely welcome a re-submission against packages/cli in the monorepo — the maintainers are active there and PRs get reviewed. Announcement: #786 · Consolidation: jsonresume/jsonresume.org#275. Thanks again for contributing during the years when this repo was quiet — it didn't go unnoticed.
