refactor: rename CLAUDE.md to AGENTS.md (#8052)

## Summary

Pure rename of CLAUDE.md files to AGENTS.md (no content changes).

## Changes

| Old Path | New Path |
|----------|----------|
| `.github/CLAUDE.md` | `.github/AGENTS.md` |
| `.storybook/CLAUDE.md` | `.storybook/AGENTS.md` |
| `browser_tests/CLAUDE.md` | `browser_tests/AGENTS.md` |
| `src/CLAUDE.md` | `src/AGENTS.md` |
| `src/components/CLAUDE.md` | `src/components/AGENTS.md` |
| `src/lib/litegraph/CLAUDE.md` | `src/lib/litegraph/AGENTS.md` |

Root `CLAUDE.md` deleted (content will be merged into `AGENTS.md` in
follow-up PR).

## Follow-up

A second PR will add glob-based guidance files and consolidate
redundancies.

+# Vue Component Conventions
+
+Applies to all `.vue` files anywhere in the codebase.
+
+## Vue 3 Composition API
+
+- Use `<script setup lang="ts">` for component logic
+- Destructure props (Vue 3.5 style with defaults) like `const { color = 'blue' } = defineProps<...>()`
+- Use `ref`/`reactive` for state
+- Use `computed()` for derived state
+- Use lifecycle hooks: `onMounted`, `onUpdated`, etc.
+
+## Component Communication
+
+- Prefer `emit/@event-name` for state changes (promotes loose coupling)
+- Use `defineExpose` only for imperative operations (`form.validate()`, `modal.open()`)
+- Proper props and emits definitions
+
+## VueUse Composables
+
+Prefer VueUse composables over manual event handling:
+
+- `useElementHover` instead of manual mouseover/mouseout listeners
+- `useIntersectionObserver` for visibility detection instead of scroll handlers
+- `useFocusTrap` for modal/dialog focus management
+- `useEventListener` for auto-cleanup event listeners
+
+Prefer Vue native options when available:
+
+- `defineModel` instead of `useVModel` for two-way binding with props
+
+## Styling
+
+- Use inline Tailwind CSS only (no `<style>` blocks)
+- Use `cn()` from `@/utils/tailwindUtil` for conditional classes
+- Refer to packages/design-system/src/css/style.css for design tokens and tailwind configuration
+
+## Best Practices
+
+- Extract complex conditionals to `computed`
+- In unmounted hooks, implement cleanup for async operations
