fix(extract): mirror plain-bullet Format 4 in parseTimelineEntries (db-source parity)

extractTimelineFromContent (fs-source) and parseTimelineEntries
(db-source extract + put_page auto_timeline) are documented as
kept-in-sync; adding Format 4 to only the fs parser left brain-authored
plain bullets invisible on the write path and `extract --source db`.
Same skip in the citation pass so a plain bullet carrying its own
[Source: ...] files exactly one entry on the db path too.
