Note

Medium Risk
Touches wallet/chain-switch RPC paths and major-version MetaMask Connect bumps; behavior change is intentional but should be validated for MetaMask and account-abstraction flows.

Overview
Bumps @web3auth/no-modal / @web3auth/modal to 11.0.2 and upgrades MetaMask Connect dependencies in packages/no-modal to @metamask/connect-evm ^2.0.0, connect-multichain ^1.0.0, and connect-solana ^2.0.0, with matching package-lock.json updates (including nested installs under no-modal).

Removes the local NULL_ON_SUCCESS_METHODS workaround and simplifies providerAsMiddleware so it forwards RPC results as-is instead of coercing undefined → null for wallet_switchEthereumChain / wallet_addEthereumChain. The deleted accountAbstractionEthRpcMiddlewares.test.ts covered that behavior.
