A fresh system (e.g. Ubuntu after apt install flatpak) has no Flathub
remote, so installing from the .flatpakrepo could not find the
freedesktop 25.08 runtime. Found in the HeiniRemote VM test 2026-10-13.

Bundles the agent as de.pc_heini.HeiniRemoteAgent on the freedesktop 24.08
runtime, mirroring the o3de-flatpak CI approach (bwrap-free build, OSTree
repo force-pushed to pages, single-file bundle attached to a Gitea release).
Compiles the agent from upstream source (newest v* tag, else main).
Sandbox notes: screen capture/input via portals need no special permission;
the PTY console uses flatpak-spawn --host for a real host shell, and a native
install's agent.toml is adopted read-only.
