* support packing deb/rpm/archlinux

* .-.

* initial test

* fix postinstall, remove execstop

* bash -> sh, create toml manually if it doesn't exist (thanks debian)

* don't forget that newline

* postrm

* comments, contrib -> packaging/linux

* contrib > packaging in .goreleaser

* actually add toml

* openrc/sysv templates

* add apk. nothing else yet

* wait, we have a ntive uninstall

* fix: merge errors, move packaging to release

* chore: remove old goreleaser conf

* ci: remove `release` dependency on `docker push`

* ci: fix release version

* ci: upload packages

* ci: try to fix json file list

* ci: replace the json file list with a txt artifact

* postremove -> preremove, skip install/remove error

* actually do preremove

* better preremove

* ci: fix

* ci: fix?

* ci: clean-up

* ci: try to change labels and filenames

* ci: fix?

* ci: fix?

* ci: add `make package` target

* ci: make labels more readable
