Feature: Introduce focused Pinia stores #43
Description
Goal
Add targeted Pinia stores for auth/session and chat runtime state where shared
reactive state now spans multiple areas.
Scope
- Introduce auth/session store for restore/auth lifecycle
- Introduce chat runtime store for timeline/runtime coordination
- Migrate only high-value shared state from ad-hoc localStorage/composables
- Keep persistence strategy explicit and minimal for MVP
Branch
feature/pinia-auth-chat-stores
Acceptance Criteria
- Auth/session lifecycle state is centralized in a dedicated store
- Chat runtime state has clear ownership in a dedicated store
- Startup and route behavior use store state consistently
- Existing behavior remains stable after migration
Test Checklist
Unit
- Store actions/getters/state transitions for auth/session
- Store actions/getters/state transitions for chat runtime
Integration
- Composables/components consume store state without regressions
- Persistence and restore paths are deterministic
E2E
- Reload/login/chat basic flow works with store-backed state
