Solidity Security Review API

Input: Solidity or Vyper smart-contract source code (or a structured contract description). Output: a structured security review with an overview, findings ordered by severity (Critical/High/Medium/Low/Info) grounded in the exact code provided, each with category, quoted evidence, impact and a concrete fix, plus a risk summary with top priorities. Built for honest triage: uncertain items are flagged "Needs verification", missing context is called out explicitly.
