feat(ask): air ask "<task>" — interactive AI task execution

New `air ask` command:
- Accepts task description from CLI
- Auto-initializes project if needed
- MainAgent classifies → LLM generates → tools execute → results
- Supports Chinese keywords (创建/写/开发/实现 etc.)
- Tool call parser supports ```json and ```tool blocks
- Executes tools first, then checks DONE (fixes race condition)
- Strips GLM </think> reasoning tags from output

Usage: air ask "创建一个C++程序打印Hello World"

Tested end-to-end with glm-5.1 on new API endpoint.
Files correctly created: 13/13 E2E gates pass.
