Migrate from Vuex to Pinia

[3aluw]

Vuex has been officially replaced by Pinia as the state management library recommended by the Vue team. Continuing to rely on Vuex adds unnecessary maintenance burden and limits compatibility with the latest Vue ecosystem.

Why migrate:

• Pinia is the new standard for Vue 3.
• Offers a simpler and more intuitive API.
• Full TypeScript support out of the box.
• Better DevTools integration and modular store design.
• Officially maintained by the Vue core team.

Suggested steps:

1. Replace Vuex dependencies with Pinia.
2. Update store logic to use the Pinia syntax (defineStore).
3. Migrate components to use useStore() instead of Vuex’s mapState, mapActions, etc.
4. Test to ensure all state and actions work as expected.
