(Migrated from github.com)

Two changes from today's session:

goldberg.steamclient + Steamless DRM shadow — opt-in support for titles that resolve Steam via the steamclient path (lsteamclient → steamclient64.dll) instead of steam_api, e.g. Patch Quest. Deploys goldberg's steamclient into the prefix + shadows Proton's legacycompat copy source, sets GAMEID/WINEDLLOVERRIDES/Steam launch env, writes a root steam_settings, and shadows SteamStub-wrapped exes with a cached Steamless-stripped copy (real install stays pristine). Verified: Patch Quest runs headlessly through splitux-together all session.

CQP env passthrough — forwards GSE_CQP_QP_I/GSE_CQP_QP_P to the seat-streamer so the vulkan-zerocopy encoder's QP point is tunable (pairs with splitux-together's CQP switch).
