Closes kcolbchain#22 - Added Chain::Solana variant with mainnet/devnet RPC defaults, LAMPORTS_PER_SOL native token, and Solscan explorer URL - Implemented SolanaChain connector backed by raw JSON-RPC (reqwest) to avoid dependency-version conflicts with solana-client / spl-* crates - Supports: balance queries, SOL transfers, SPL TransferChecked - ATA derivation (spl_ata) requires no external SPL crate dependency - Added unit tests: test_spl_ata_derivation, test_balance_local_validator (validator test auto-skips when solana-test-validator is not running) - Updated examples/multi_chain.rs to include Solana balance query - Updated README.md: Solana marked Supported, Cosmos remains Planned Co-authored-by: Ishant5436 <ishant.p@somaiya.edu>
