• [x] I have searched existing issues to see if the issue has already been opened, and I have checked the commit log to see if the issue has been resolved since my server was last updated.

Describe the feature

Following the same pattern we've followed since like, 2020: When the latest ubuntu LTS comes out AND BECOMES AVAILABLE AS A GITHUB ACTIONS RUNNER: we will upgrade and pick whatever compilers and toolchain things that come packaged with that runner - and then update our Windows requirements as necessary.

This will include, but not be limited to:

• C++ compiler
• Use of std::format, std::expected, and other goodies that will come from having C++20 across the board
• All the additional errors and warnings that will become available with new compiler tooling
• New Python, etc.
• Not having to build LuaJIT on certain runners in CI
• Updating the version of spdlog we use to use the version that uses std::format and not fmtlib
• Check versions of MariaDB, etc.
• OpenSSL, etc.

Also new CMake version

And then update all the docs, and yell very loudly from the rooftops that people need to upgrade their stuff (we can also block builds and have helpful error messages - not that people read the error messages we already produce ;_;)

Boo, std::expected is C++23, we'll need to use nonstd

It looks like GH has started to roll out access, will be able to do this soon: https://github.com/actions/runner-images/pull/9754

Ubuntu 24.04 is still listed as Beta

https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2404-Readme.md

We may be restricted on Linux by what C++ compilers are available for use on OSX:

https://github.com/actions/runner-images/blob/main/images/macos/macos-14-Readme.md

Like, if we want to use the clang-18 that's available on the Ubuntu 24.04 release, only clang-15 is available on OSX, etc.
