feat(qwen-agent): add instrumentation for Qwen-Agent

[sipercai]

Description

This PR adds loongsuite-instrumentation-qwen-agent: OpenTelemetry instrumentation for Qwen-Agent using ExtendedTelemetryHandler from opentelemetry-util-genai. It emits GenAI semantic-convention traces for agent runs, LLM calls, ReAct steps, and tool execution (invoke_agent, chat, react step, execute_tool), registers an opentelemetry_instrumentor entry point, and includes unit tests plus VCR-based integration tests.

Fixes #11

Pull request overview

Adds a new LoongSuite OpenTelemetry instrumentation package for the Qwen-Agent framework, integrating ExtendedTelemetryHandler to emit GenAI semantic-convention spans for agent runs, LLM chat calls, ReAct steps, and tool execution, along with CI/tox wiring and test coverage (unit + VCR-based integration).

Changes:

• Introduces loongsuite-instrumentation-qwen-agent with wrappers around Agent.run, BaseChatModel.chat, Agent._call_llm, and Agent._call_tool.
• Adds unit tests validating span creation/hierarchy and VCR-backed integration tests with recorded HTTP cassettes.
• Wires the new package into tox-loongsuite.ini and GitHub Actions test/lint workflows.
