Highlights

• Added VA-API HEVC 4:4:4 decoding support by detecting matching HEVC 4:4:4 profiles and YUV444 render target formats.
• Support retained HEVC 4:4:4 VA-API frames through the libplacebo DRM PRIME zero-copy rendering path.
• Fall back from HEVC 4:4:4 to HEVC 4:2:0, H.264 hardware decoding, or H.264 software decoding when compatible hardware support is unavailable.
• Patch the Parsec SDK 6.0 negotiation gate for the injected FFmpeg decoder so HEVC 4:4:4 can be negotiated through the client-owned decoder path.
• Require libva 1.8.0 for HEVC SCC Main444 10-bit support.
• Replace --no-subsampling, --no-acceleration, and --no-hevc with a single --video-decoder option.
• Add explicit hardware and software HEVC and H.264 decoder modes with defined codec, color, acceleration, and fallback policies.
• Default to hw-hevc-444 with fallback through HEVC 4:2:0, H.264 hardware decoding, and H.264 software decoding.
• Restructure CLI usage output, README documentation, and the man page so decoder modes are grouped under video options.
• Avoid duplicate HEVC fallback warnings when unavailable HEVC hardware decoding has already selected H.264.
• Restore README content regressions, fix USB redirect placeholders, and raise badge cache timing.
• Extract source checks into a reusable CI script and add CI lint checks for standalone comment spacing and spacing between function definitions.
• Add and normalize function-level and in-function source comments across the client modules.
