Fixes #15329

What was wrong

Games played fullscreen, mostly with a controller, still hit the screensaver and then the lock. The only idle inhibit for games is the per-class rule on steam (plus GeForce NOW, Moonlight, RetroArch), so nothing covers Proton steam_app_* windows or games from other launchers. A commenter on #15329 hit the same thing with Rocket League from Heroic.

Fix

One catch-all rule in default/hypr/windows.lua:

o.window({ fullscreen_state_internal = 2 }, { idle_inhibit = "fullscreen" })

• Any window in true fullscreen (mode 2) holds off idle while it's on a visible workspace, no matter which launcher started it.
• Full width (SUPER + ALT + F, maximized, mode 1) is left out on purpose. Hyprland's fullscreen inhibit mode alone counts maximized too, so a Full width browser would otherwise never lock.
• It sits before require("default.hypr.apps"), so app rules like noidle (always) still win.

Why general instead of per-launcher

Class rules only cover the launchers someone remembered to list. Heroic, Lutris, itch, native games and emulators all use different classes, and Wine/Proton class names change per game. Fullscreen is the thing they all share.

Relation to #15401

Complements it. #15401 inhibits on focus for steam_app_*, which also covers windowed Steam games. This covers fullscreen windows from any launcher.

Testing

• Hyprland --verify-config (0.57.0): config ok.
• No suite test for a one-line config rule.
• hyprland-default-config-test.sh passes.
• config-test.sh fails on the PKGBUILD timesyncd check, but it fails the same way on plain quattro, so it's unrelated.
• Not tested in a live session with a real game.
