v0.3.1

• Added "Total time" to the runs overview — summed generation time, the same measurement /results shows
• Show a run's note as readable text in the /results run picker instead of a hover bubble
• Added this changelog, and cut a GitHub release from the same tag that publishes the image
• Gate the published image on make check, so a red suite no longer produces a latest
• The sidenav build string links to the commit it was built from, or to its release
• Fixed the PROMPTRACK_TAG example, which suggested a v prefix the published image tags don't carry
