chore: drop exports nothing imports

knip 6.44 follows the members a dynamic import reads, and the Insights
page reads two of the derived barrel's: the barrel now exports those two,
whose building blocks are imported from their own modules. BAND_VAR had
no reader, and the drawer re-exported useResettableValue for a test that
only imports nextResettableValue. The size and version-stamp baselines
take the lower numbers.
