Refactor TypeScript API to use object-based parameters

[Copilot]

Refactors all TypeScript client constructors and public methods from positional parameters to object-based configuration for better extensibility and future parameter additions.

Changes

Client constructors

• AutoLLMClient: now accepts options object with inline type
• All model-specific clients (Claude4_5Client, Gemini3Client, GPT5_2Client, GLM4_7Client, Qwen3Client): updated to accept inline options object

Public methods

• streamingResponse: now accepts options object { messages, config }
• streamingResponseStateful: now accepts options object { message, config }

Usage updates

• Test suite
• Playground integration
• Documentation and examples (both root and TypeScript README)

API Changes

Constructor:

// Before
new AutoLLMClient('claude-sonnet-4-5-20250929', apiKey, baseUrl, clientType)

// After
new AutoLLMClient({ 
  model: 'claude-sonnet-4-5-20250929',
  apiKey,
  baseUrl,
  clientType 
})

Methods:

// Before
client.streamingResponseStateful(message, config)

// After
client.streamingResponseStateful({ message, config })

Breaking change: All existing code using the old API signatures will need to be updated.

Original prompt

把 typescript 的类和方法输入都改成对象类型，方便之后兼容更多的输入参数，修改以后可以使用 AutoLLMClient({model: 'claude-sonnet-4-5-20250929'}) 的方法调用（breaking-change but better API）

Pull request overview

Refactors the TypeScript SDK’s public API to use object-based parameters (constructors + streaming methods), and updates downstream usage (tests, playground, docs). Also extends tracing to persist the model name and adds additional OpenAI Responses streaming event handling.

Changes:

• Switch TypeScript client constructors and streamingResponse* methods from positional args to { ... } options objects.
• Update TypeScript tests and playground integration to the new call signatures.
• Extend tracer output to include the model in both TS and Python implementations.
