Note

Medium Risk
Changes account-switching chain resolution and connection reuse logic, which can affect wallet switching flows across EVM/Solana namespaces. Risk is mitigated by added/updated unit tests but could still impact edge cases in multi-chain setups.

Overview
Fixes account switching so the SDK does not unnecessarily change chains when switching to a linked account that shares the same chain namespace as the current active chain; processSwitchAccountResult now resolves a resolvedSwitchChainId and uses it for connector creation, connect, and setCurrentChain.

Also aligns code/tests with the newer primaryConnectorName/ConnectedAccountInfo naming (removing reliance on connectedConnectorName), and updates the demo dashboard to read chain ID from web3Auth.currentChain and gate wallet services off primaryConnectorName.
