What changed in JsonParser.parseReader(JsonReader) between the supplied base and head revisions, including its temporary parsing mode and restoration of the caller's setting on return or throw? Cite exact base and head source spans and distinguish declared from executed behavior.

Source observation: the saved Boolean lenient and setLenient calls are replaced by a saved Strictness value and setStrictness calls. Both versions call Streams.parse(reader) and restore the saved setting in finally. Called-method behavior and actual test coverage are not established here.

Recorded rationale: no recorded-source evidence included.
Human decision: none recorded.
Not determined: runtime outcomes, full mode coverage and downstream compatibility.
