ginuerzh a9d94e7009 fix(metadata): nil-Metadata from NewMetadata(nil), missing float32 in GetFloat; add doc comments and tests ...

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.
