* chore: Initial database scaffolding
This implements migrations and code generation for interfacing with a PostgreSQL database.
A dependency is added for the "postgres" binary on the host, but that seems like an acceptable requirement considering it's our primary database.
An in-memory database object can be created for simple cross-OS and fast testing.
* Run tests in CI
* Use Docker instead of binaries on the host
* Skip database tests on non-Linux operating systems
* chore: Add golangci-lint and codecov
* Use consistent file names
This implements an initial GitHub Actions workflow for us - to be run on PRs and on `main` commits.
This just implements a really simple `style/fmt` check - running `prettier` on the `README.md`.
I assumed we'll stick with using a top-level `Makefile` for commands like in `m` and `link` - but open to alternatives, too!
Since I was adding a `package.json` and `node_modules` for this, I realized we were missing `.gitignore`s, so I added some a subset of the ignore files from `coder/m`
