PR Summary

Medium Risk
Adds a new CLI command that hits a public Sim API endpoint (with a built-in unauthenticated HTTP fallback), plus tests that execute the command and may rely on live network responses, which can introduce flakiness.

Overview
Adds dune sim evm supported-chains, a new public (no-auth) command that fetches /v1/evm/supported-chains and prints either raw JSON or a human-readable table of per-chain endpoint availability.

Refactors cmd/sim/evm to consume a small SimClient interface sourced from command context when available, and otherwise uses a new minimal HTTP client for this public endpoint; includes basic command-level tests for both text and JSON output.
