 * A class to manage Supabase operations for jsPsych experiments

 * ```typescript
 * const supabaseManager = new SupabaseManager(supabaseConfig, {
 *     tableName: "my-experiments",
 *     metadata: { version: "1.0.0" }
 * });
 * ```
 *
 * IMPORTANT: Before using this manager, make sure to:
 * 1. Create the table in your Supabase dashboard
 * 2. Set up Row Level Security (RLS) policies to allow operations:
 *    - Go to Authentication > Policies
 *    - Add a policy for INSERT: "Enable inserts for authenticated users" with USING(true)
 *    - Add a policy for SELECT: "Enable select for authenticated users" with USING(true)
