Parses read.export lines into per-account lineage plus the embedded checkpoint. Blank lines
are skipped. Throws when the first line does not declare the EXPORT_FORMAT marker, on
an unknown line type, and on empty input — a truncated or foreign file fails loudly instead
of parsing to an empty ledger.
