Note

Low Risk
Single constant-map addition and changelog update; low blast radius limited to enabling pricing for an additional chain.

Overview
Adds Chiliz Mainnet (0x15b38 / CAIP-19 eip155:88888/...) to CodefiTokenPricesServiceV2’s SPOT_PRICES_SUPPORT_INFO map so CHZ native-asset spot pricing can be fetched via the Price API.

Updates the assets-controllers changelog to document the new CHZ/Chiliz pricing support.
