Basic implementation using Zustand to store values. For now just the
ChatModel and the SystemPurpose that are currently active. This enables
app-wide synchronization and automated persistence. Meaning we can now
have settings (and in future conversations) which are persisted and
synchronized.
API keys have not been migrated yet, because we need to import them from
the existing localStorage key, for a smooth transition.
Warning: this adds 203kb of JS to the app, more than 4x'ing
the size of the app. Will remove if not worth it. Uses Sandpack
from Codesandbox.io, which stands up full execution environments
for the code.
