Description

We already have a router instrumentation for TanStack Router, but we also want to add a proper e.g. @sentry/tanstack SDK.

Currently, TanStack Start relies on Vinxi on the backend but this will be replaced by Nitro before TanStack Start releases version 1.0.0.

• Add a guide in docs about manually setting this up
• Add to in-product onboarding for manually setting this up
• Add actual proper SDK, eventually - this will need proper Nitro support!
