This PR updates the GH Action docker workflow to crossbuild the docker
image for ARM using QEMU.
This theoratically works but takes about for a clean build 2.5 hours,
which may or may not be tolerable for each commit on `main`.
A action run where the dependencies are already cached needs about 15
minutes with this PR.
* Begin moving to sqlx for local too
* Stupid scanners should just have a nice cup of tea
Random internet shit searching for /.env or whatever
* Remove diesel and rusqlite fully
* Switch to Cargo workspaces
Breaking things into "client", "server" and "common" makes managing the
codebase much easier!
client - anything running on a user's machine for adding history
server - handles storing/syncing history and running a HTTP server
common - request/response API definitions, common utils, etc
* Update dockerfile
