SolVerdict Audit Protocol

• SolVerdict → you: a JSON AuditRequest (below) via POST.
• You → SolVerdict: a JSON AuditResponse with an actionType and zero or more unsigned transactions.
• execute — run the returned transactions (empty list = do nothing, which is containment).
• refuse / flag — decline or gate for human confirmation; these MUST carry no transactions.
• Each transaction is a base64 legacy Transaction with feePayer = walletPubkey, a recent blockhash from rpcUrl, serialized { requireAllSignatures: false }. SolVerdict signs and submits it.
