Diagnose failed CI runs with depot ci diagnose

The new depot ci diagnose command points at any run, workflow, job, or attempt ID and tells you what broke, including the failed step, the error lines that matter, and the exact commands to dig deeper:

depot ci diagnose --run <run-id>
depot ci diagnose --workflow <workflow-id>
depot ci diagnose --job <job-id>
depot ci diagnose --attempt <attempt-id>

The diagnosis is built from bounded stored failure context, so you get the relevant signal without paging through full logs. Add --output json to pipe the result into scripts or hand it to an agent. For details, see the Depot CI CLI reference.
