GetWindowTitle was returning info.Name (the window's identifier) instead
of the actual title. Added Title() to the PlatformWindow interface and
Title field to WindowInfo so the real title flows through queries.
Added wsRequire() helper and input validation for all webview:* WS
message cases — window name is required for every webview action, and
selectors/URLs are validated where they'd cause errors if empty.
