Subject: [PATCH 3/4] Add transcript warning and refactor
GetIncludeTranscript()
Summary:
Add warning to 'statistics dump --transcript=true' when
interpreter.save-transcript is disabled, helping users understand
why transcript data is empty.
Also refactor StatisticsOptions::GetIncludeTranscript() to use
value_or(false) instead of the verbose has_value()/value() pattern
to address PR comments.
