enricobuehler b7cb75a48a fix(host): dual identical GPUs stream again — self-heal the IDD-push ring onto the driver's real render adapter ...

A box with two identical GPUs (twin RTX 4090s in the field report) died out
of pipeline retries with driver_status=2 (DRV_STATUS_TEX_FAIL, detail
0x80070057): SET_RENDER_ADAPTER pinned the driver to one twin at monitor ADD,
but the ring open re-ran the GPU picker, whose max-VRAM tie is settled by
DXGI enumeration order — which follows the primary display that the vdisplay
flow itself moves mid-session. Ring on one twin, swap-chain on the other →
the driver can't open the shared textures, and every retry repeats the same
wrong pick.

- wait_for_attach: TEX_FAIL becomes a typed AttachTexFail carrying the render
  LUID the driver reports in the shared frame header (written before the
  texture opens, so valid on failure) — the error now names both adapters
  instead of guessing "mismatch?".
- open_inner: on AttachTexFail with a different, non-zero driver LUID, rebind
  the ring there and reopen ONCE. Both candidates are real GPU adapters, so
  NVENC keeps getting a device it accepts.
- gpu::enumerate (Windows): sort the inventory by LUID so the max-VRAM tie,
  the env-substring first match, and twin occurrence numbering are stable for
  the boot instead of tracking the primary display.
- manager: record the ADD-time render pin on Monitor and warn on reuse when
  the current pick has moved away from it (the pick only takes effect on the
  next monitor create; /display/release forces one).
- pf_vdisplay: drop the "ADD render adapter DIFFERS from pinned" warn — the
  ADD reply carries IDARG_OUT_MONITORARRIVAL.OsAdapterLuid (the IddCx DISPLAY
  adapter, verified on-glass), not the render GPU, so the check compared
  unrelated LUIDs and fired on every ADD.

Verified on the RTX 4090 box: single-GPU streaming is unchanged (IddPush +
NVENC AV1 session, no new warnings). The rebind path needs a twin-GPU box —
until validated there, /display/release remains the manual recovery.
