Tao Chen df32fc02f0 feat(python): Add MCP client OTel spans per GenAI semantic conventions ...

Implement MCP client spans per the OTel GenAI Semantic Conventions for MCP
(https://opentelemetry.io/docs/specs/semconv/gen-ai/mcp/#client).

Operations instrumented:
- initialize: CLIENT span capturing MCP session setup
- tools/list: CLIENT span for tool listing (per-page)
- prompts/list: CLIENT span for prompt listing (per-page)
- tools/call: CLIENT span (nested under execute_tool when called via FunctionTool)
- prompts/get: CLIENT span

Span attributes follow the MCP semantic conventions:
- Required: mcp.method.name
- Conditional: error.type, gen_ai.tool.name, gen_ai.prompt.name
- Recommended: gen_ai.operation.name, mcp.protocol.version, mcp.session.id,
  network.transport, server.address, server.port

Transport-specific attributes per subclass:
- MCPStdioTool: network.transport=pipe
- MCPStreamableHTTPTool: network.transport=tcp, network.protocol.name=http
- MCPWebsocketTool: network.transport=tcp, network.protocol.name=websocket

All span creation gated behind OBSERVABILITY_SETTINGS.ENABLED.

Closes #3624
Closes #4697
