Prisma MCP Server

## relationMode = prisma with onUpdate = Restrict We test 2 different schemas - `primary-key` where the id referenced in the relation is the Primary Key, we run the tests on all databases (except on MongoDB we only run 1 test, as the second test would need to mutate the primary key `_id`, which is immutable). - `at-unique` where the id referenced in the relation is NOT the Primary Key, it is an `@unique` field, we run the tests on all databases.
