I'm making steps to simplify our build dependencies, consolidating our C
compiler requirements so we only depend on Zig.
Before, we used Zig for x64 but not for arm64. This meant that users
using an ARM dev machine would need to install `build-essentials` and
Zig. We also required MinGW-w64 on Windows, which is a pain to install
since it can be provided by a bunch of different tools, the smallest of
which is like a 2GB install.
NodeJS 20 is almost EOL so I'm updating our workflows to use NodeJS 22.
This does not change anything about our app, which will still use NodeJS
20 until Electron shifts away from it. NodeJS 22 is fully
backwards-compatible with NodeJS 20 so there's no issue from a testing
standpoint.
