Handle maintainer rebase request with explicit handoff

[Copilot]

This PR thread included a maintainer request to rebase the branch for the Snyk-driven ESLint upgrade. The update addresses that request by validating branch state and responding with the correct next action under current execution constraints.

• Comment handling

  • Processed the new reviewer comment (@copilot+gpt-5.3-codex rebase) as an actionable rebase request.

• Branch/state verification

  • Confirmed current branch cleanliness and recent commit context before responding.

• Rebase handoff

  • Since rebase operations are not permitted from this environment, posted a direct maintainer-facing instruction to use GitHub Update branch (or perform local rebase), then continue review on the refreshed branch.

I can’t run `git rebase` from this environment.
Please use GitHub’s Update branch button (or rebase locally), and I can continue from there.
