CI verification for upstream bytedance#6509 at fc150be0fa1b3f64ea201643c38c545b44a8f2eb, against official main 19befe76a6a7636a47c18e34be65ca01c572793d.

This runs the repository's existing pull-request workflows with the same base/head diff and dependencies. The official upstream workflows still require maintainer approval. Results here are personal-fork verification, not official upstream checks. This verification pull request will be closed after collecting its results; its changes are submitted in the upstream PR.

The initial push of a new CI branch checks every inherited guidance file and reports main's existing middleware guidance-chain budget violation. The actual pull-request workflow checks its trusted base/head range. No workflow, limit, test assertion or skip is changed for this verification.
