Adds a parallel install path for Debian/Ubuntu hosts alongside the existing
Arch/Omarchy/Hyprland one. The Arch path is untouched at runtime; everything
new is gated on $DISTRO and (for headless) $COMPOSITOR.
Highlights:
- lib/distro.sh: detect_distro + pkg_install/pkg_remove/ca_anchor_path/
ca_update_trust dispatch helpers
- lib/packages.sh: Ubuntu sunshine install pulls LizardByte's official .deb
from GitHub releases (override via SUNSHINE_DEB_URL/SUNSHINE_DEB_VERSION);
GPU encoder packages branch per $DISTRO:$GPU_VENDOR
- bin/sunshine-stream-{do,undo,prestart}-sway.sh + files/sway-headless.*:
swaymsg-based headless capture path for hosts without Hyprland. sway runs
under a systemd-user unit that sunshine.service depends on via drop-in.
- lib/preflight.sh: clearer NVIDIA driver guidance on Ubuntu (we don't install
the driver - too many branch/kernel/Secure-Boot variants); sway-aware
headless preflight
- lib/certs.sh + lib/verify.sh + uninstall.sh: distro-aware CA trust anchor
(Arch: /etc/ca-certificates/trust-source/anchors + update-ca-trust;
Debian: /usr/local/share/ca-certificates + update-ca-certificates)
Verified on Ubuntu 24.04: ./install.sh --doctor --headless loads cleanly,
distro/GPU/compositor detection report the right values, all pre-install
failures correspond to the actual missing pieces.

# Sunshine global_prep_cmd `do` hook for the Sway-based headless capture path

# On client connect:
|
|
# - Ensures a HEADLESS-1 output exists on the running sway session

# - Resizes it to the client's negotiated mode (WxH@FPS)

# This script intentionally mirrors the Hyprland do-hook's shape so debugging
|

# transfers across the two paths.
