AP2 Mandate-Chain Validator

Reference implementation for AP2 v0.2 mandate-chain validation. Paste your Intent → Cart → Payment mandate JSON trio and validate: signature-chain integrity (parent hash linkage), scope and spend-limit consistency, TTL/expiry at validation time, over-spend detection, and Human-Not-Present (HNP) autonomous-flow flags. Load a built-in PASS or FAIL scenario to explore the validation model, then export conformance test-vector fixtures for CI integration.
