fix: add fallback for reexported symbols and correct barrel pagination

When hasExportedCol is false (older databases), reexported symbols now
use the same findCrossFileCallTargets fallback as direct exports instead
of silently returning an empty array.

_pagination.hasMore now accounts for reexportedSymbols in barrel-only
files where direct results are empty, preventing API consumers from
truncating results without knowing more pages exist.

Impact: 2 functions changed, 1 affected
