feat(rules): add Vue coding-style and composables/reactivity rules
Add rules/vue/coding-style.md:
- <script setup> Composition API enforcement
- Naming conventions (PascalCase components, useCamelCase composables)
- SFC structure order, props/emits/slots patterns
- Vue 3.5+ reactive props destructure with native default values
- Template conventions, import ordering
Add rules/vue/hooks.md:
- ref() vs reactive() guidance and replacement pitfalls
- Vue 3.5+ reactive props destructure (version-specific: Vue<3.5 loses reactivity, 3.5+ reactive by default with watch limitation)
- computed() purity rules, watch vs watchEffect comparison
- Watcher cleanup with onWatcherCleanup() (Vue 3.5+) and onCleanup callback
- useTemplateRef() (Vue 3.5+) replacing name-matched plain refs
- Composable conventions (use prefix, reactive returns, MaybeRef inputs)
- shallowRef/shallowReactive for large data structures
