Solana Program Read

Read a Solana account or program's on-chain state — the analogue of an EVM contract read. Uses RPC getAccountInfo (jsonParsed): returns whether the account exists, its owning program, whether it is executable (i.e. it IS a program), lamports / SOL balance, data size, and decoded state for known program accounts (SPL token mints/accounts, system, stake). Arbitrary accounts return owner + raw data info. Read-only, keyless.
