Stage 8: developer profile with dprofile (0.6.0)

dprofile (das-helpers 0.2.0) installs profiles listed in
/usr/share/das/profiles: packages from the Void repository between a
snapper pre/post pair, their services and groups, subordinate IDs and a
shared root mount for rootless Podman, and optional IDEs from Flathub.
The installed system can't see the Das OS repository yet, so a das-dev
metapackage could not be installed there; Void packages always can.

The dev profile: Go, Python, Node.js, Git, Docker, Podman and command-line
tools everywhere, VS Code (code-oss), Meld and Flatpak on a desktop, with
Android Studio and JetBrains IDEs on demand. Questions come before sudo.

das-welcome (das-tools 0.4.0) gets a developer profile row that runs
dprofile in a terminal; das-server-install mentions it at the end.
