fix(server): settle error session exits - #7854

This check requires the following CI step(s) to pass, but they did not:

• Check — failure

The check has been skipped before any work was dispatched, so this run cost nothing. GitHub counts only success, skipped, and neutral as passing — the same three conclusions that satisfy a required status check on a protected branch. To wait for a step without requiring it to pass, move it from requires to waitsFor in your .macroscope/*.md front matter.
