The dictionary TryReadComplexType overload (added in microsoft#9983) manually iterated dictionary entries but treated \ metadata as regular dictionary keys. When a dictionary value object contains \ (for reference tracking), the manual iteration read it as a dictionary entry key and tried to parse the reference ID string as an InputExampleValue, corrupting the reader position. Fix: skip \ metadata entries (via TryReadReferenceId) when iterating dictionary keys, consistent with how other converters handle reference tracking metadata. This preserves the manual iteration needed to handle \$-prefixed user keys (like \) while correctly ignoring serialization metadata. Fixes regression from microsoft#9983.
