Subject: [PATCH 1/2] fix(extension): Stabilize update marker

Use the upstream README timestamp for the generated settings marker instead of formatting the local update time. This keeps the marker deterministic across operating systems and avoids locale-specific settings churn.

Subject: [PATCH 2/2] fix(extension): Preserve marker wording

Keep the generated marker compatible with the previous text shape while making the timestamp deterministic. This limits the change to the timestamp source and reduces risk for ad-hoc readers.
