[compat-canary] Prisma adapter breaks against latest Prisma

The weekly compatibility canary failed building/testing the Prisma adapter against the latest released Prisma.

This is an early warning that an upcoming Prisma version introduces a breaking change (API/class relocation, removed method, etc.) before a customer hits it. See the failing run for the exact error:

Stable releases are unaffected — the supported pinned version still builds. Resolve by updating the adapter for the new Prisma version, then this issue can be closed (the canary will reopen it if the break recurs).

Start with the failing compatibility run at https://github.com/awslabs/aurora-dsql-orms/actions/runs/32000969994 and identify the exact Prisma adapter failure against the latest released Prisma. Compare it with the supported pinned version, update the adapter for the changed API, and verify that the canary builds and tests successfully.
