end of summer refactor (#31)

* crates: `bot-*` -> `discord-bot`

I didn't really need all these crates to be split :/

* discord-bot: revamp http impl

also handles the new errors reported by teawieAPI

* crates: split http backend

this can be reused easily

* git-tracker: short-circuit boolean logic

We don't need to check if the commit is a descendant of the HEAD of the
branch if it *is* the HEAD

* nix: fenix -> nixpkgs

* treefmt: add actionlint

* nix: use docker arch names for containers

* ci: use actions-rust-lang actions

* nix: drop ci dev shell

* git-tracker: init ManagedRepository

this logic can be shared

* ci: use nix for clippy scan

* discord-bot: better handle unmerged PRs

* ci: fix treefmt check

* nix: fix clippy check

* .env.template: update crate names

* git-tracker: use remote name for remote name

i was half asleep

* discord-bot: handle merged PRs that aren't found in any tracked branches

* git-tracker: make collect_statuses_in() return a Vec

* discord-bot: add more PR info with response

fixes #18
