The two review tabs, runs and try-out, are one: /review. It is a column of
three sections: try a classification and the classifier settings, each a
folded bar (the settings' bar says what they are now), then the recent runs,
always open. The settings had been pinned under the try-out form; they are now
a section of their own. A new Disclosure primitive is the folding bar, a
native details wearing the Panel's classes, so the folded and open sections
read as the same surface.
/review-runs and /review-tryout are gone, with no redirect.
A page to try a review classification against a real PR: repo, PR number and one or more classifications (name, description, polarity, threshold). Run posts to the controller's try-out endpoint and polls until the run is done or failed, saying it is running meanwhile, then shows the review's table, the overall verdict and the head commit. A row that could not run shows its error in place of a reason, and a failed run shows its error. The inputs stay so the run can be edited and repeated. Nothing is stored and nothing is posted to the forge. Route, nav entry and a section in docs/swarm/ui.md.
