Chain support, with sources

We only add a chain when the maker's own docs name it. "EVM-compatible" alone counts for no specific chain. A testnet-only record means the page we checked only shows testnet; it isn't a finding that mainnet is unsupported. This is what the docs say, not a test or security review.
