Split the packages, publish releases from Gitea Actions, release 0.1.0

make deb now builds two packages: jarl-cli (the CLI, its completion and
the ACME hooks, no scripts) and jarl (the server), which depends on
jarl-cli of the same version.

Pushing a v* tag runs .gitea/workflows/release.yml: it tests, builds the
tarballs, the CLI for Linux, macOS and Windows (make cli-dist) and the
.debs for amd64 and arm64, then scripts/gitea-release.sh creates the
Gitea release and uploads the .debs to the Debian package registry, so
servers install and upgrade with apt. The stats package's inode lookup
is split by OS so the CLI builds for Windows.
