Split release chat verification into three validated test-line shards and balance other server suites across five runners using the measured native Runner integration cost. Retire each chat case's fixtures after assertions, preserve complete test coverage, and exercise the real shard CLI in PR tests. Co-Authored-By: Paperclip <noreply@paperclip.ing>
