Add devcontainer for web and AI contributorsPublic

Let me take a quick look at the project to give you a useful answer.

I'd skip it. The project is a Go CLI tool with no services, databases, or complex runtime dependencies. Anyone contributing just needs Go installed and go build works. A devcontainer would add a file to maintain for a setup that's already one command.

If you start getting contributors who struggle with environment setup, it might be worth revisiting, but for a project like this it's overhead without much payoff.

Good point, that changes the calculus. Codespaces (and things like GitHub's edit-in-browser flow) rely on devcontainers, and AI coding agents like Devin or OpenHands use them too. Without one, those environments have to guess at the setup or fall back to defaults that may not have the right Go version.

The maintenance cost is basically zero for a Go project - it's a small JSON file pointing at a Go image. Worth doing.
