Windows: DLSS watermark off, check script, 310.7.0 pair, shorter docs

- Set Disable.Watermark on the game path (the Linux shim already does);
  [DLSS] ShowWatermark = true keeps NVIDIA's stamp.

- Always write d4r\d4r_nvngx.log in player mode. It was skipped when the
  launcher gave the game a valid stderr pipe, e.g. Steam.

- Accept NVIDIA's 310.7.0 + _nvngx 32.0.15.9636 as "less tested" pins.
  Native kernels are still gated by PTX identity, so a different DLL
  falls back to translated kernels.

- Add d4r-check.ps1 (ok/MISSING/note lines with a fix for each; -Report
  writes a bug-report ZIP) with 15 fixture tests.

- package-windows-release.ps1: -Architectures subset, ships the check
  script, GPU registry and one GPU-query tool.

- Add a shorter WINDOWS_README.txt; trim README's Windows section and
  merge in the RX 9060 XT / distributor-DLL notes.

- Diagnostic probe accepts preset 12 (L).

Tested on RX 7700 XT without a game: loader and shim start-up, K and M
synthetic NGX frames with both DLL pairs (finite output, native kernels
used). Not tested in a game.
