Solana Transaction Decoder

Decode a Solana transaction by signature and explain what it did — the cross-chain analogue of the Stacks Transaction Decoder. Uses Solana RPC jsonParsed decoding: returns status (success/failed) + error, fee, slot, block time, fee payer, the programs involved, a per-instruction summary (program + parsed type/info for known programs like System and SPL Token), the SPL token balance changes (mint, owner, delta), and SOL balance changes per account. Read-only, keyless.
