Resolves #35299. Triggers on issue create. Tested the same code in https://github.com/iansltx/fleet/actions/workflows/auto-tag-unreleased-bugs.yml; check the associated issues on that repo for the comments (or lack thereof). Grabbed a bunch of issues from this repo to properly catch edge cases. This only looks at issue body so the titles including released/unreleased are for testing convenience and have no effect on whether a comment happens either way. I expect we'll need to dial this in further but this errs on the side of categorizing something as unreleased because shipping regressions due to mis-triage is worse than finding out a bug is released when we weren't sure to begin with. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: iansltx <472804+iansltx@users.noreply.github.com> Co-authored-by: Ian Littman <iansltx@gmail.com> Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>
