feat(ai): add claude code agents sdk integration

[shellmayr]

Add instrumentation for the claude-agent-sdk package, which provides
a Python interface to interact with Claude Code CLI.

The integration captures:

• gen_ai.system: "claude-agent-sdk-python"
• gen_ai.operation.name: "chat"
• gen_ai.request.model / gen_ai.response.model
• gen_ai.request.messages (when PII enabled)
• gen_ai.response.text (when PII enabled)
• gen_ai.request.available_tools
• gen_ai.response.tool_calls
• gen_ai.usage.input_tokens / output_tokens / total_tokens
• gen_ai.usage.input_tokens.cached

Instrumented methods:

• query() async generator function for one-shot queries
• ClaudeSDKClient.query() and receive_response() for interactive sessions
