fix(sdk): correct the realtime token example and fail-fast the docs bundle

The realtime skill's TriggerButton example named its token `publicAccessToken`
while passing it to useTaskTrigger, which contradicts the skill's own warning
that a read token cannot trigger a task. Renamed to `triggerToken`.

bundleSdkDocs now throws instead of warning when no doc sources are found, so a
broken skills dir fails the build rather than shipping the SDK with missing docs.
