/**
* libSQL implementation of `UserDataStorageConnector`.
*
* Deliberately shaped like `connectors/supabase/supabase.ts` method for method,
* so the two can be diffed when behaviour is in question. The differences are
* confined to three places:
*
* 1. **Ids.** Postgres defaults `id` to `uuid_generate_v4()`. SQLite has no
* uuid function, so creates that do not carry an id generate one here.
* 2. **JSON columns.** Objects and arrays are stringified going in; `query.ts`
* decodes them coming out.
* 3. **Stored procedures.** The five RPCs the API calls become explicit
* transactions at the bottom of this file.
