Context

Both agents and agentic workflows perform actions like LLM calls, tool executions, and MCP calls. Right now, there's no built-in tracing to understand what happened during these workflows. Adding tracing will help track every step an agent takes, using standard GenAI trace formats, so teams can debug and monitor agent behavior more easily.

Acceptance Criteria

• Generate traces for:
  • LLM calls
  • Tool calls
  • MCP calls
  • Calls to various storage, embeddings APIs
• Use OpenTelemetry GenAI semantic conventions(https://opentelemetry.io/docs/specs/semconv/gen-ai/) for trace attributes
• Support exporting traces using OpenTelemetry Collector
