The eNAV importer read only the HLD securities sheet, so a credit fund's
loan book (its largest asset) never reached NAV. SATS Credit Fund showed
$3.6M of securities while holding a $46.3M loan to Fold Holdings.
Parse the HLD-LOANS schedule alongside HLD: each loan becomes a holding
and position valued at principal plus accrued interest, flowing into
holdings, invested cost, and the quarter NAV. Adds test coverage and
bumps the package to 0.2.47.
