docs(roadmap): gamescope multi-user research (deferred); render->capture parked

Document the gamescope multi-user (independent-desktops) research and defer it:
the current shared host-lifetime input/audio/mic vs the per-session plumbing it
would need — per-instance EIS sockets + a per-session injector + per-session
null-sink audio routing + per-session mic — and why it's not worth it now (a large
multi-file refactor for the niche multi-user-on-one-box case, while the common
multi-device scenario is already covered by the shared-desktop multi-view
concurrency that landed). New gamescope-multiuser.md + roadmap section 14
(concurrent sessions: multi-view done, multi-user deferred).

Also park render->capture in section 12: pipewire-rs 0.9.2 exposes no
buffer-meta / raw-pointer / stream-timing API, so reading SPA_META_Header.pts
would need raw spa_sys FFI into the working capture hot path — disproportionate
for the smallest glass-to-glass term; g2g is effectively complete as
capture->present (the stage-2 presenter measures it).
