Extension Data Viewer

Every Caffeine app ships with auto-generated controller-only queries for browsing stable variables like Map, Set, Array, and List types. You declare a stable var, and the compiler gives you a paginated `__<var>` query that traps for non-controllers. It's purely for admin dashboards and debug panels, not user endpoints. The skill documents what's already wired into the template via `caffeineai-data-viewer` and the `--generate-view-queries` flag. One thing to remember: pure collections aren't supported, and you should never roll your own `__` prefixed members or lean on these queries for public APIs.
