PHP 8.4 support

[dkarlovi]

Since PHP 8.4 is now fully out, seems it could be supported here.

Hmm, unsure why there's no renovate pipeline for that.

This PR should be it: https://github.com/Roave/BackwardCompatibilityCheck/pull/769/files

Perhaps you can check what's up there?

Looking at the pipeline, composer.json is requesting newer versions of stuff, but composer.lock (which is committed in the repo) isn't getting updated by renovatebot in the same PR, even though the docs claim they should be kept in sync?

[Ocramius]

That's probably because renovate can't run an update on 8.2.x then 🤔

We still need vimeo/psalm to release here first: not possible to upgrade earlier.

I'd suggest helping upstream here: vimeo/psalm#11035

@Ocramius it seems the PR is basically done, but the review process is taking a while and it will cause a new major of Psalm anyway. It's generally a good idea not to install the QA tools as dev deps, you don't rely on them directly, you're just using them like a hammer in which case installing them in a separate root in a isolated way (via a separate composer.json or managed via https://github.com/bamarni/composer-bin-plugin) is way more preferable.

It's a tool used as part of the runtime, not separately: it is part of the main dependencies, and not really a plugin/separate.

Happy to accept patches for https://github.com/Roave/infection-static-analysis-plugin/ that solve this at architectural level.
