PreFlight Checker

Pre-flight checks for agents before they act: npm package trust, GitHub repo health, domain liveness, and EVM token contract safety. Each returns a deterministic score or verdict with the signals behind it, so an agent can decide whether to trust a dependency, a link, or a token before committing to it.
