App journey: each run opens on its verdict, the audit opens on real audits

Run page: one line under the title says what broke, whether a fresh container proved the fix, and one button (the PR, the fix, or the failed step)
Human-checked summaries from the examples index replace raw patch reasons, so Dagster no longer reads as a docs bug
A run with skipped steps no longer reads as "works as written"
Facts drop from 8 to 4: steps, fixes, proof, cost
Run page nav says Runs and Audit, like the rest of the site
Audit page: the empty command box stays hidden until a repo is entered, and real audits come before the explainer
Runs page: the cost note is one line instead of a retold plan
