Every chain and the route of each capability

The directory an agent starts from. One entry per chain Chord serves, with its constants (native asset, wrapped native, dollar anchors with real decimals, explorer) and, for each capability, the route that serves it on that chain. A capability the chain does not have is null: the data routes grew chain by chain, so this is the one place that says where to read what. Solana is listed with id: null and base58, case-sensitive addresses; its quote and swap are /sol/trade/quote and /sol/trade/send while its trade lane is open to everyone. A chain that is not public yet appears only for a caller with an API key.
