Complete career timeline

The fighter's FULL multi-promotion career: native tracked bouts (richest data, source: "native") merged with the wider multi-promotion career record (source: "history"). Spans every promotion they fought in — not just launch orgs. Every key is present on every row (null when unknown), and each row carries status (one vocabulary across both sources: win, loss, draw, no_contest, cancelled, upcoming, unknown), method_normalized, time_seconds and an opponent object ({id, slug, name}, ids only on native rows) beside the raw result / method / time strings. Newest first; meta.truncated is true when the history rows hit their 500-row cap. source_slug names the publisher: ufcalendar on native rows; on history rows an official publisher (ufc-official, wikipedia, a promotion's *-official), else public-records.
