Remove deprecated worldSafeExecuteJavaScript option

Editor assessment

The subject states the removal exactly: the deprecated worldSafeExecuteJavaScript option is gone. The chore type fits a deprecation cleanup, and the absent scope is tolerable. No body is present, which is acceptable because the subject names the retired option and the removal completely, and the deprecation itself supplies the context, though the migration path for remaining users would have been worth a line. The PR reference is well-formed. Imperative mood, no trailing period, compact length. A clear, self-sufficient cleanup message.
