Software H.264 decode at 1080p struggled on a low-power viewer (Intel
UHD 620 laptop on battery / power-save governor), surfacing as choppy
motion and A-V drift even though the host encode side was clean. mpv's
auto hwdec picks vaapi/nvdec/etc. when available and silently falls
back to software when not, so the default is strictly safer.
Applied to both the headless banner recipe and the interactive
player-picker spawn args.
Bare `pixelpass` now opens a dialoguer-driven Host/View menu instead of
going straight to host mode. Host path copies the ticket to the system
clipboard via arboard with silent print-only fallback. View path
prompts for the ticket, then after the local listener binds prompts
mpv-vs-VLC and spawns it detached (setsid + null stdio) so the player
survives pixelpass exiting.
Headless invocations (`pixelpass <ticket>`, `pixelpass --repair`)
unchanged. Per spec at ~/Documents/pixelpass-interactive-mode-spec.md.
