✨ Daggerverse: modules should display their engine version

[jpadams]

What are you trying to do?

Need to know engine version that a module was built with so can know if a module is compatible with my engine version.

Want to filter for modules by engine version.

Why is this important to you?

Modules created with an engine version different from the one I'm running might not behave properly.

How are you currently working around this?

You can look at the dagger.json in a module's git repo.

Hm, I agree that this is currently an issue, but I don't think the solution is to encourage users to check the engine version in daggerverse.

IMO, if a dagger.json engine version is less than or equal to the engine version, we should always be able to run it - for old versions, we can introduce backwards compatibility to provide an old API for old modules. For newer modules... we could just refuse to run them for now? Something like #7031 but for modules?

That said, that's a longer term commitment to breaking less and to provide a more stable experience - so maybe temporarily having this info in daggerverse might be a good shout?
