chore: drop GitHub issue URLs from pre-handshake guard log messages

The runtime console.error/warn strings in App._assertInitialized and
AppBridge.replaceRequestHandler linked to a tracking issue. Issue URLs
in runtime logs are brittle and send developers to a discussion thread
rather than actionable docs; the message itself already says what to do.
JSDoc @see links retained.
