Subject: [PATCH] fix: use dynamic import for AI SDK to resolve tiktoken WASM
 build error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Convert static import of executeToolWithAgent to dynamic import inside the
POST handler. This prevents the AI SDK (and its tiktoken dependency) from
being loaded at build time, which was causing WASM loading errors.

**Why this fix works:**
- Next.js 16 + Turbopack tries to analyze routes at build time
- tiktoken requires tiktoken_bg.wasm which can't load during static analysis
- Dynamic imports defer loading until runtime, avoiding build-time WASM issues

**Changes:**
- Remove: `import { executeToolWithAgent } from '@/lib/ai-agent/tool-executor-agent'`
- Add: `const { executeToolWithAgent } = await import('@/lib/ai-agent/tool-executor-agent')`
  inside the stream start() handler

Build now completes successfully. Route is properly marked as dynamic (ƒ).

Resolves: "Error: Missing tiktoken_bg.wasm" during Next.js build
