+Trace Module for PraisonAI Agents.
+
+Provides lightweight action tracing for the `output="actions"` mode.
+Shows agent lifecycle events, tool calls, and final output without
+verbose internal details.
+
+Zero Performance Impact:
+- All imports are lazy loaded via __getattr__
+- NoOpSink is the default (zero overhead when not used)
+- Disabled emitter has near-zero overhead
+
+Usage:
+    from praisonaiagents import Agent
+    
+    # Simple usage - shows action trace
+    agent = Agent(instructions="...", output="actions")
