A turn that OpenCode stopped could end with nothing on screen: the
session.error event was only turned into a sidebar badge, its message was
dropped (the notification expected a different shape than OpenCode sends),
and a send that was accepted but never answered looked the same as success.
- The chat shows what OpenCode reported under the last message while that
turn is the latest one, and names a user message an idle session has left
unanswered for five seconds.
- The last 20 session errors are kept in memory and listed in the status
report (Ctrl/Cmd+Shift+L, also `__opencodeDebug.statusReport()`), next to
rejected sends, the managed OpenCode process's last error and stderr
tail, and the OpenCode and desktop log file locations.
- The OpenCode health probe hits /global/health instead of a route that
does not exist, and probe URLs resolve against the page for web runtimes.
