simple_network_handler_supabase

Supabase error handling for the simple_network_handler family: map AuthException, PostgrestException, StorageException, and FunctionException to typed failures via a declarative SupabaseErrorRegistry, executed through SupabaseHandler.safeCall (or the SupabaseNetworkHandler static facade).

See the main simple_network_handler README for full documentation; this package follows the same patterns for the Supabase SDK instead of Dio.
