ERC-7730 Transaction Decoder

Trusted: curated descriptors from ethereum/clear-signing-erc7730-registry (pin a commit SHA). Untrusted: Sourcify and generateDescriptor — never confidence: "high". New protocol metadata goes to the official registry, not this repo. This playground opens in Production (officialOnlyPolicy(), no Sourcify). Exploration opts into officialOrLocalPolicy() and Sourcify. Wallets in production use officialOnlyPolicy() or attestedPolicy(). Every decode shows source, confidence, warnings, and trust.accepted.
