### Description This PR improves the comments and test coverage of the service discovery metadata customizers. - Adds doc comments to metadataServiceURLParamsMetadataCustomizer, MetadtaServiceVersionCustomizer, and ProtocolPortsMetadataCustomizer, explaining the metadata key written, the source of the parameters, how empty values are handled, and the overwrite behavior. - Adds unit tests covering metadata param extraction (IncludeKeys filtering, empty-value skipping, port/protocol always appended), version writing (tri -> v2, other/empty protocol -> v1, non-local storage skipped, invalid JSON skipped), and protocol port writing (empty list, empty protocol skipped, unparsable port recorded as 0).
