[jrconlin]

Update all sub crates to same core version.
Update library crates to latest version.
Address clippy issues in middleware.

Update for pending package release

I don't think you should do workspace lib versioning like this. Recommend keeping each crate with it's own version field. Other shared fields below here make sense though.

I go back and forth about this quite a bit. The plus being when we tag a release, do a library check, etc. we only have one location we need to update.
The downside is that these crates are very loosely bound together under a fairly arbitrary collector.

I'll revert the version number change for now, but I still kinda would like to keep the version work simplified where possible.
