Gabriel Brown 359fb922aa Install the four applications this desktop assumed you had
Helium was already declared. Podman Desktop is on Flathub, so it joins the
flatpak list beside the podman it fronts.

RustDesk was the interesting one. panama-doctor has checked `rustdesk.service`
for as long as it has existed, and autostart.lua works around the tray that
service spawns -- so RustDesk was already part of this desktop, installed by
nothing. The flatpak cannot register a root-owned system service, so unattended
access needs the RPM.

Claude Code has no RPM and no flatpak either, so it takes the official installer
and keeps itself updated afterwards.

Neither pins a version. sunhat pinned upscayl 2.11.5, LACT 0.5.4 and a fedora-40
RPM, and every one of those was a 404 within a release cycle; the RustDesk URL is
resolved from whatever the latest release happens to be. Both are skipped when
already present, and a failure is logged and stepped over rather than aborting a
stage that has already installed the desktop.

That leaves three exceptions to the dnf-or-flatpak rule, all named in one place
with a reason each. The dependency contract now knows they are installed out of
band, so probing for them with `command -v` is not read as an undeclared
dependency -- narrowly, per command, so a genuine omission still fails.

# Every external command Panama's own scripts invoke must be installed by
# Panama's own package lists.
#
# This exists because the lists had drifted badly. jq is used by thirty-one call
# sites across the helpers and the contracts; kitty has a full shipped config
# and a dock pin; tmux and btop have shipped themes that the color scheme
# switches. None of the four were declared. So a fresh machine that followed
# this repository's own install instructions would not have them.
#
# The failure is quiet by design, which is what makes it worth a test: the
# helpers are written to report "not installed" rather than crash, so a missing
# dependency presents as a feature that silently is not there.
#
# Commands from coreutils and the shell itself are not checked -- nothing
# installs those separately, and listing them would be noise.
