"""User profile schema and LangGraph Store CRUD.

Storage is split into two namespaces to avoid the read-modify-write race
between profile-edit writes and OAuth-callback token refreshes:

* ``["profiles"]`` — user-editable settings (model, effort, default_repo).
* ``["oauth_tokens"]`` — encrypted GitHub OAuth access token + email.

Each upsert only touches its own namespace, so the two flows can't clobber
each other's fields even when they interleave.
