Pierre Kisters 13d7a437f8 docs: split feature details into docs/

One page per feature group (sessions, keyboard, launcher menu, dashboard, SteamVR debugger, Firefox, Jellyfin, UI patches, changes outside Nix) and the full options table in docs/options.md.

The Frame runs two graphical sessions at once; most workarounds exist because of their differences:

	Steam / VR session	Nested Plasma desktop
Compositor	gamescope	KWin (nested, shown as a VR window)
Displays	X display `:0` (apps show as floating VR windows)	own Wayland + Xwayland `:2`
D-Bus	the outer session bus, `/run/user/1000/bus`	a private bus
`XDG_RUNTIME_DIR`	`/run/user/1000`	its own
systemd user manager	yes	not reachable

Consequences:

Wallet: there should be one kwalletd6, on the outer bus; apps started from the desktop would otherwise start a second one whose secrets VR can't see. Prefix launchers' Exec= with steamFrame.session.busEnv (session settings).
User services: home-manager skips reloadSystemd when switching from the desktop terminal, so steamFrame.session.services talks to the outer user manager directly.
Launchers: the "+" menu only sees ~/.local/share/applications (not ~/.nix-profile/share), so entries are written there, shadowing Flatpak/package entries with the same ID.
Keyboard layout: KDE's layout only affects the nested desktop (keyboard layout).
Clipboard: separate per session (clipboard sync).
Firefox: the sessions can't see each other's Firefox, so a second instance stops at the locked profile (desktop profile).

Switch (home-manager switch) from a terminal in the nested desktop, so clipboard-sync restarts with the desktop's environment.
