Implement cosmos.directory support to automatically fetch chain parameters (denom metadata, APR, slashing params) and provide RPC fallback. This feature works orthogonally with any provider (default, namada, etc.) and requires only a new 'chain_name' config field. If not set, defaults to lowercase of the chain display name. Key changes: - Add 'chain_name' config field to ChainConfig - Add cosmos.directory data types and API fetching with 10s timeout and 30m caching - Use cosmos.directory as fallback for denom metadata (after ABCI query fails) - Use cosmos.directory as fallback for APR/chain info (after ABCI query fails) - Automatically try cosmos.directory RPC proxy when configured nodes fail - Updated example config with chain_name documentation Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
Add non-negative check before converting int exponent to uint32 to prevent potential integer overflow when processing cosmos.directory denom units. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
