docs: add design spec for Jellyfin hardware transcoding on jupiter 84cec9e935

Jupiter's Intel iGPU is configured at the OS level but Jellyfin has no
access to it, so transcodes run on CPU only and stutter.

feat(jellyfin): grant iGPU access for Quick Sync hardware transcoding 5235f5abcb

fix(jupiter): add oneVPL/MFX runtime for QSV hardware transcoding adb7fcfad7

HEVC HDR transcodes were failing with "Error creating a MFX session: -9"
because intel-media-driver only provides VAAPI, not the separate
oneVPL/MFX runtime QSV needs to create a hardware session.

fix(jupiter): add Intel compute-runtime for OpenCL HDR tone-mapping 86e7f9c1a8

HDR HEVC transcodes were failing with "Failed to get number of OpenCL
platforms: -1001" (CL_PLATFORM_NOT_FOUND_KHR). The tonemap_opencl
filter jellyfin-ffmpeg uses for HDR-to-SDR tone-mapping needs an OpenCL
ICD, which intel-media-driver/vpl-gpu-rt don't provide on their own.
