Code Review

This pull request introduces support for several new chains and tokens by adding their asset constants, NEAR intent mappings, and reserved fee amounts. The changes cover Berachain, Gnosis, Stellar, XLayer, Monad, Plasma, Litecoin, and BitcoinCash. The implementation is straightforward, adding new entries to existing data structures. I've pointed out a minor issue related to what appears to be incomplete support for Stellar USDC, where a constant is added but not used, and a related mapping is commented out. It would be cleaner to remove this code until the feature is fully ready.
