from_date/to_date are inclusive ISO dates (YYYY-MM-DD); app filters on the
meeting app name (case-insensitive substring, e.g. "zoom").

By default this does NOT return the transcript text — a long meeting would
flood your context. It returns metadata plus `path`: a rendered transcript
file you should open with your own file tools, reading only the ranges you
need. To pull lines inline instead (e.g. no filesystem access), pass `limit`
(and optional `offset`) to get that slice of segment lines directly.
