Owner

Adds a "Gaming (gamescope)" wayland-session the display manager launches on its
own DRM seat. On its own seat gamescope owns input and Steam Input drives the
cursor natively (the Steam Deck model) — the only way to get controller-as-mouse.
Nested in niri, gamescope can't own the seat and Steam falls back to a frozen
XTest cursor. Seating it via the DM also gives Steam a real login session, so its
bwrap/runtime work (a hand-rolled systemd seat broke that).

gamingSessionPackage: [Desktop Entry] running gamescope --backend drm -e -- steam -gamepadui, registered via services.displayManager.sessionPackages.
steamos-session-select stub turns Steam's "Switch to Desktop" into an exit:
touch a sentinel → the foxtrot-gamemode-exit.path user unit quits Steam +
gamescope, returning to the greeter.

Status

The session seats and Steam runs in it (no cap/bwrap breakage). Still to confirm
before merge: controller-as-mouse actually moving the cursor in-game (per the
verify-before-merge habit). Opening now per always-open-a-PR.

Stacked on #656 (Steam migration). The greeter that makes login controller-only is
#664 on top of this.

A wayland-session the display manager launches on its own DRM seat, so gamescope
owns input and Steam Input drives the cursor natively (the Steam Deck model) —
the only way to get controller-as-mouse. Nested in niri gamescope can't own the
seat and Steam falls back to a frozen XTest cursor. Letting the DM seat it also
gives Steam a real login session (bwrap/runtime work).

steamos-session-select stub turns Steam's 'Switch to Desktop' into an exit:
touch a sentinel -> the foxtrot-gamemode-exit.path unit quits Steam + gamescope,
returning to the greeter.
