Add modules/hostel-wifi.nix: per-SSID MAC randomization (iwd), disable
mDNS/LLMNR/NetBIOS, reject hostile IPv6 RAs, firewall LAN-side probing,
an nftables killswitch target allowing only tunnel egress + captive-portal
endpoints, NTS-secured time via chrony, and a captive-portal helper.
Import left commented out; toggle via 'untrusted on|off'.
acpi.ec_no_wakeup=1 stops EC interrupts from thrashing s2idle, and a
dconf system-db override disables gsd-power's sleep handlers so logind
owns all sleep/idle policy (gsd was re-waking before HibernateDelaySec).
Split lid/suspend policy by power source (s-t-h on battery, plain suspend
on AC), map power key to hibernate, drop HibernateDelaySec to 15min while
re-validating thermals, and disable USB-device wakeup via udev.
Add opensc (PKCS#11) and pcsc-tools, enable pcscd, and add a udev rule
granting access to the built-in reader (2ce3:9563), which the shipped
CCID rules miss (pcscd hit LIBUSB_ERROR_ACCESS). Configure Firefox to
load the OpenSC PKCS#11 module for TLS client-cert auth and force-install
the Web eID extension.
Add nix-flatpak flake input and modules/gaming.nix managing Flatpak
remotes/packages declaratively: Bolt (Jagex launcher for RS3/OSRS) and
Sober (Roblox). Add Heroic and hyperplay-ext, plus Proton-GE for Steam.
Drops the old imperative runescape-launcher.
