fix(collect-i18n-node-defs): refactor to run ComfyNodeDefImpl only in browser context (#5775)

## The Problem

The `collect-i18n-node-defs.ts` script started failing ~3 weeks ago when
Vue nodes were introduced ([commit
006e6bd57](https://github.com/Comfy-Org/ComfyUI_frontend/commit/006e6bd57),
[PR #4263](https://github.com/Comfy-Org/ComfyUI_frontend/pull/4263)).
The issue stems from:

1. **Import chain bringing Vue components into Node.js context:**
   ```
   collect-i18n-node-defs.ts
     ↓ imports
   ComfyNodeDefImpl (from nodeDefStore.ts)
     ↓ imports
   useSubgraphStore (from subgraphStore.ts)
     ↓ transitively imports
   executionStore.ts
     ↓ imports
   ChatHistoryWidget.vue (Vue component!)
   ```

2. **TypeScript `declare` fields causing Babel errors:**
   ```
TypeScript 'declare' fields must first be transformed by
@babel/plugin-transform-typescript
   ```

## This Solution vs PR #5515

### PR #5515 Approach (Complex)
- Adds custom Babel plugins and configurations
- Implements automatic browser globals injection
- Requires **47,517 additions, 9,469 deletions**
- Modifies the entire Playwright babel transformation pipeline

### This PR's Approach (Simple)
- Uses dynamic imports to defer module loading until runtime
- Avoids Babel compilation of problematic TypeScript/Vue files
- **Only 40 lines changed** in a single file
- No configuration changes needed

## How This Fix Works

```typescript
// Instead of static import that Babel tries to compile:
// import { ComfyNodeDefImpl } from '../src/stores/nodeDefStore'

// We use:
// 1. Type-only import (erased at runtime)
import type { ComfyNodeDefImpl } from '../src/stores/nodeDefStore'

// 2. Dynamic import at runtime (bypasses Babel)
const { ComfyNodeDefImpl: ComfyNodeDefImplClass } = await import(
  '../src/stores/nodeDefStore'
)
```
