Add a `-V`/`--version` flag to CLI tools

[tgross35]

Since a lot of us are using installs from git, it's currently tricky to figure out which version we are actually running. Would it be possible to put this information in the CLI?

This can just be done with vergen-git2 / vergen-gix / vergen-gitcl (depending on what is already in-tree) and having a CLI flag that outputs some combination of CARGO_PKG_VERSION, VERGEN_BUILD_DATE, VERGEN_GIT_DESCRIBE, and VERGEN_GIT_SHA.

Hey @tgross35 , thanks for the suggestion.

We'll figure out how to embed this version information -- but also for future reference, if you weren't installing from git, what package source would be preferable for you? e.g. homebrew, APT, conda/pixi etc

I think crates.io would be ideal if that's possible to do again, since it covers us across different systems. But part of the motivation for installing from git is also that we'd like to use features that have arrived since the 2024 version, so we'd still need a new release for any distribution to be useful.
