[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-canary run linked in the issue and inspect its exact Prisma adapter build or test error. Locate the adapter entry point from that run, update it for the latest Prisma release, and verify that both the canary and the supported pinned version still build and test successfully.
