Levi Woodard 0d6da8c24a Add headless-primary streaming mode + off-screen window self-heal ...

Desktop lives on a persistent HEADLESS output that Sunshine captures; DP-1
mirrors it when present, so streaming works whether or not the physical monitor
is on. Fixes workspace/window orphaning when the monitor powers off (the old
'HEADLESS mirrors DP-1' design collapsed when DP-1 disappeared).

- bin/sunshine-headless-primary.sh: apply (idempotent topology + rescue),
  rescue (recenter off-screen floating windows), watch (self-heal on monitor
  add/remove and on windows that open off-screen).
- bin/sunshine-prestart.sh: delegates to the manager's apply.
- docs/HEADLESS-PRIMARY.md: full rationale + the ufw stale-subnet gotcha.

Not yet wired into install.sh; configured directly on JARVIS via monitors.conf
and autostart.conf (tracked in the dotfiles repo).
