- Added detailed documentation in `AUTH_CONTEXT_MIGRATION_PLAN.md` for lessons learned during Phase 1 of the `AuthContext` migration.
- Highlighted critical implementation insights, including refactoring `useAuth` to call Zustand hooks internally, strict type safety with the `AuthState` interface, and dependency injection via `AuthProvider`.
- Defined updated architecture for provider placement and emphasized the importance of documentation, barrel exports, and hook compliance with React rules.
- Included comprehensive examples, verification checklists, common mistakes to avoid, and future-proofing guidelines.
- Introduced a new `AuthContext` with Dependency Injection to replace direct `useAuthStore` access, enhancing E2E testability.
- Migrated authentication core components (`AuthInitializer`, `AuthGuard`, `Header`) and hooks (`useAuth`, `useUser`) to use `AuthContext`.
- Updated test suite:
- Refactored unit tests to mock `AuthContext` instead of `useAuthStore`.
- Enhanced E2E test helpers to inject mock auth stores for authenticated and admin scenarios.
- Verified API client interceptors remain compatible with the new setup.
- No breaking changes; maintained 98.38% test coverage.
