Subject: [PATCH] Fix wallet add/switch-network: use a clean RPC, not the WC
 proxy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AppKit's built-in networks advertise rpc.walletconnect.org/v1/?chainId=…&projectId=…
as the chain RPC. Wallets reject that query-string URL as "Invalid URL" when
adding/switching the network — Trust showed "Invalid URL", desktop MetaMask
looped on Switch Network, and the mobile buy failed because the switch to Amoy
never completed. Clone the chain with our clean public RPC before handing it to
AppKit/Wagmi.
