Verify against a real Frame; switch clipboard to Klipper

The headset desktop is nested Plasma in gamescope with no wl-copy/xclip,
so paste-to-frame.sh now calls Klipper over plasmashell's D-Bus bus.
connect.sh, push.sh, paste-to-frame.sh and install-apps.sh were exercised
on SteamOS 0.3.0 (build 20260922); docs record what was confirmed.
Cross-provider review skipped at Alex's request (Astra quota exhausted).
