NewMetadata(nil) previously returned a nil Metadata interface, causing panics on direct .Get()/.IsExists() calls. Now returns an empty map. GetFloat added float32→float64 promotion, matching GetString behavior. Doc comments for all 13 exported symbols across both packages. 41 unit tests (11 metadata + 30 util) at 100% coverage.
