Auto-captures a video's width/height/duration at file-select and persists them on
the 30078 — the durable foundation for a future "shorts" vertical feed (filter on
height > width) and for the NIP-71 mirror's short-kind selection.
- js/utils/videoProbe.js: probeVideoMetadata(src) loads metadata into a hidden
<video> (element injectable for tests); resolves {width,height,duration} or null.
- UploadModal: probes the selected file (objectURL) in the background and threads
width/height/duration into the publish payload.
- videoPayloadBuilder: persists width/height/duration in content (publish) and
preserves them across edits; normalizers exported.
- convertEventToVideo: exposes video.width/height/duration → the mirror builder
already uses them (portrait ⇒ 34236 short + imeta dim).
tests: probe resolution (incl portrait + error/timeout → null); content persist +
parse; portrait⇒34236 / landscape⇒34235 mirror selection; edit preserves dims.
Mutation-verified earlier on the mirror short-selection.
