Expand description

Deserializes a Polymarket game ID as an opaque identifier.

The Gamma API returns the field in several shapes: an integer on GammaEvent, a numeric string on most GammaMarket records, and a composite <uuid>:<away>:<home> string on some sports markets. The value identifies a venue-side fixture and is never used for arithmetic, so it is kept verbatim rather than parsed into a number. Both null and -1 (or "-1") are the “no game” sentinel and map to None.
