Use OR operator to require both Browser and Protocol-Version fields. Simplified catch block to generic error message since specific wrong-port cases are already handled by the validation blocks above.
Options page now validates that /json/version returns valid CDP JSON (with Browser/Protocol-Version fields) rather than accepting any HTTP 200 response. This prevents false success when users mistakenly configure the gateway port instead of the relay port (gateway + 3).
Helpful error messages now guide users to use "gateway port + 3" when they configure the wrong port.
The extension relay server authenticates using an HMAC-SHA256 derived
token (`openclaw-extension-relay-v1:<port>`), but the Chrome extension
was sending the raw gateway token. This caused both the WebSocket
connection and the options page validation to fail with 401 Unauthorized.
Additionally, the options page validation request triggered a CORS
preflight (due to the custom `x-openclaw-relay-token` header) which the
relay rejects because OPTIONS requests lack auth headers. The options
page now delegates the check to the background service worker which has
host_permissions and bypasses CORS preflight.
