Rebuild configuration.md into a complete PUNKTFUNK_* reference (verified against config.rs, the host.env templates, and the env read sites): core, gamescope/session-following, compositor, video quality, gamepads, audio, Windows host, auth/paths, perf tuning, diagnostics, and client-side knobs. Rework bazzite.md: it now documents both Steam Gaming Mode (gamescope) and the KDE Plasma desktop with auto-detect/session-following, attach vs managed, and the Desktop screencast + kde-desktop-setup.sh input grant — previously it only described the managed gamescope model.
