Builds the full export-capability report for the WebCodecs encoding path.
Every value is probed live through VideoEncoder.isConfigSupported — per codec: overall support
at the export size, passing bitrate modes, hardware availability, the standard resolution
ladder, and the passing bitrate interval. The overall supported flag reproduces the export
worker's fallback ladder for the active (possibly user-forced) codec, so it answers "would an
export started right now find a usable encoder configuration". With dryRun: true the selected
configuration is additionally verified by actually encoding a few frames.
