feat: add new stores for cron, locale, providers, script, shared data, skills, and user info

- Implemented `cron` store to manage scheduled tasks with CRUD operations.
- Created `locale` store for language settings with persistence and system language detection.
- Added `providers` store to handle provider accounts and configurations with API interactions.
- Developed `script` store for managing automation scripts, including recording and execution.
- Introduced `sharedStore` for managing shared data across components.
- Established `skills` store for fetching, installing, and managing skills from a marketplace.
- Created `userinfo` store for user authentication and session management.

chore: update path aliases from `@store` to `@stores` in TypeScript configuration and Vite config
