Contract Deploy Tracer

No RPC method answers "when was this deployed", so this binary-searches the chain for the first block where the address had code — roughly 25 requests instead of millions. Reports the deployment block, date, age in days and bytecode size, and flags contracts deployed in the last day or month, since age is the strongest single signal available before you approve anything. The binary search needs an RPC that serves historical state; a pruned endpoint will fail partway and the app says so rather than reporting a wrong block. Age is a signal and not a verdict — an old contract can still be malicious, and a new one can be perfectly legitimate.
