# Story: Persist Project Selection

## User Story
**As a** User
**I want** the application to remember the last project I opened
**So that** I don't have to re-select the directory every time I restart the app.

## Acceptance Criteria
*   [ ] Backend: Use `tauri-plugin-store` (or simple JSON file) to persist `last_project_path`.
*   [ ] Backend: On app startup, check if a saved path exists.
*   [ ] Backend: If saved path exists and is valid, automatically load it into `SessionState`.
*   [ ] Frontend: On load, check if backend has a project ready. If so, skip selection screen.
*   [ ] Frontend: Add a "Close Project" button to clear the state and return to selection screen.

## Out of Scope
*   Managing a list of "Recent Projects" (just the last one is fine for now).
