An AI-driven skill that ingests disparate data formats (CSV, JSON, XLSX) and builds a structured Supabase database. It automatically infers relationships, types, and schema names.

* `supabaseUrl`: String - Your project URL.
* `supabaseKey`: String - Service role key for schema creation.

## Capabilities

- **Type Safety**: Automatically converts strings to dates/numbers where appropriate.
- **Batched Uploads**: Handles large historical datasets without crashing.
