New Rule: no-store

[baseballyama]

Motivation

Svelte 5 allows state management using runes. On the other hand, we can also manage state using store. This rule prohibits the use of store, thereby restricting state management to runes only.

Description

DO not use store. Please use runes instead.

Examples

<!-- ✓ GOOD -->
let count = $state(0);

/* ✗ BAD */
import { writable, readable, derived } from 'svelte/store';
