Subject: [PATCH] feat(gaming): unify and automate game window rules

Refactors 'modules/home/gaming.nix' to use a unified 'mkGameRules' function.
Applies full gaming rules (monitor 0, workspace gaming, immediate, fullscreen) to:
- Steam apps (class:^steam_app_\d+$)
- Gamescope, Lutris, Heroic
- Wine/Proton windows
Preserves manual overrides in the 'games' list.
