The systemd service runs as root with no User=, so _run_as_user() had no
SUDO_USER/USER to drop privileges to and launched Steam as bare root with
no DISPLAY/XAUTHORITY/DBUS session - its CDP port never opened. Add an
explicit STEAM_ENFORCER_DESKTOP_USER env var (set in the unit, substituted
by install.sh) so the enforcer always knows which desktop user owns the
Steam session, regardless of how it was launched.
Also fix a hardcoded _CDP_PORT=8080 colliding with an already-running
local service bound to 0.0.0.0:8080: requests to 127.0.0.1:8080 always
hit that service instead of steamwebhelper (which only bound
[::1]:8080), so CDP detection could never succeed even with the user
fix. Move to 9222, the conventional Chrome DevTools port.
Verified live: journalctl shows CDP ready and games hidden within ~7s
of a service restart, Steam running as the desktop user (not root).
guard-lib was folded into github.com/kuhyx/utils as a subdirectory;
update the install.sh detection/install path from $HOME/guard-lib to
$HOME/utils/guard-lib to match.

Adds `block-gaming <days>`: uninstalls Steam, kills/uninstalls known game
launchers, and blocks Steam + game-website domains (hosts + iptables) for a
fixed number of days with no in-app way to lift it early. Enforcement is
tamper-resistant via guard-lib's package-block (bind-mounted lock file) and
re-asserted every enforce tick.
Also migrates store_blocker.py's hosts-file locking from raw chattr/mount
calls to guard-lib's file-guard, using the new `sync` subcommand (not
`pacman-relock`) so our own legitimate edits aren't reverted as drift.
Fixes found during live verification:
- iptables never blocked real IPs because DNS was resolved after /etc/hosts
already redirected every blocked domain to 0.0.0.0 locally - reordered so
iptables resolves first.
- Game-website blocks only covered bare apex domains; sites that
301-redirect to www (e.g. newgrounds.com) sailed right through - added
automatic www. variant generation.
- Launchers (e.g. prismlauncher) were only killed, never uninstalled -
added best-effort pacman-package removal keyed off /proc/<pid>/exe.
