Persist memory sessions when vite reloads

[penx]

We use kv sessions in production, but want to have the option to fall back to something local during development. This should mirror how our kv sessions work - so not cookie based sessions as they require committing the session on each change.

Memory session storage looks like the best choice, but every time vite reloads it seems to clear the sessions.

To add to this, every time I go to a new route that vite hasn't yet loaded the dependencies for, I get a "new dependencies optimized" in the vite console followed by the sessions being reset.

Is it possible to make createMemorySessionStorage persist sessions between vite reloads?

Here's an example for createPersistentMemorySessionStorage.

It basically works the same a regular memory storage, but adds the internal Map object as a global singleton to survive restarts.
