Syncs the twente-vortexflow card, pipelines and figures on the Hub with the reviewed state on GitHub (open-h/OpenH-RF).

Both pipeline_chirp.yaml and pipeline_short_imaging_pulse.yaml gain the grid reconstruct.py uses: x +/-80 mm, z 50-100 mm on a 1600 x 700 grid. Without it zea falls back to a default grid and the figures do not reproduce.

Adds the seven figures the card shows. Five were already referenced but sat at the folder root on GitHub and were never uploaded here, so the links were dead: the setup schematic and its side view, the microbubble size distribution, the reference B-mode, and the camera-to-ultrasound mapping. assets/vortex_street.gif is the new header loop, pairing the Photron high-speed camera view with the B-mode reconstruction frame for frame from track_0, so both show the same instant of the vortex street. assets/main.png is the release image and is not embedded in the card.

Two text fixes come with it: the reference B-mode caption said left/right where the panels are stacked top/bottom, and the reconstruction command now matches the script, which takes ZEA_FILE and FRAME at the top rather than CLI flags.

Update — common card layout. The card now follows the layout shared by every OpenH-RF dataset: frontmatter with a name, a stand-alone title, the hero image with an italic caption linking the sample it shows, Description, Contributor(s), Creation Date and the standard CC BY 4.0 text, then a new Processing the Dataset section (the zea process command where the pipeline carries the whole reconstruction, and the reconstruct.py link) followed by Dataset Format, which opens with the zea version. Hard line breaks are gone so the Hub wraps paragraphs itself; the longer sections keep their content.

Update — GH#38 (contributor corrections). The transmit is now described as a diverging wave, since the curved array has no transmit delays, rather than a plane wave. The card's tables are also numbered. Both pipelines change to a 1536 x 480 grid (x +/-80 mm, z 50-100 mm, was 1600 x 700) with a -50 to 0 dB dynamic range, and the reference B-mode and camera-mapping figures are regenerated to match.
