[JavaScript] TanStack Start SDK

[mydea]

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!

@mydea FYI, Start is working on removing the Vinxi deps:

Vinxi will be removed before version 1.0.0 is released and TanStack will rely only on Vite and Nitro. The commands and APIs that use Vinxi will likely be replaced with a Vite plugin or dedicated TanStack Start CLI.

We are looking forward to use Sentry with TanStack Start React.

Would love some guidance on setting up the source maps properly, too! I can't get this to work with the standard Sentry vite plugin right now:

[plugin vite-plugin-tanstack-start-ensure-global-middleware] Sourcemap is likely to be incorrect: a plugin (vite-plugin-tanstack-start-ensure-global-middleware) was used to transform files, but didn't generate a sourcemap for the transformation. Consult the plugin documentation for help (x194)

@kieranm I haven't looked at sourcemaps yet but will write a guide soon. Until then, this particular warning would require fixing upstream in vite-plugin-tanstack-start-ensure-global-middleware. But, I should also note that this is merely a warning and does not indicate that sourcemaps will not work at all.
