chore(data): add the first Honkai Impact 3rd snapshot

Fetched by the runner rather than by hand, so the whole path is evidenced:
robots allowed at Crawl-delay 1, the 307 followed to the live version, canParse
satisfied, eventCount 16. The lane now builds from live bytes instead of
falling back to the checked-in fixture.

Kept out of the source commit because a snapshot is data this repository
rewrites on a schedule, and the fixture is the pinned copy that proves the
parser.
