Title: 🧠 Add pipeline execution timing and performance tracing

Description

Improve visibility into pipeline performance by tracking execution timing and tracing steps.

Goals

• understand performance bottlenecks
• improve debugging and observability
• provide insight into pipeline execution

Requirements

• track execution time per pipeline step
• log timing information using tracing
• include optional debug/verbose mode for detailed output
• integrate with existing logging system

Acceptance Criteria

• execution time is tracked per step
• timing is visible in logs
• debug mode shows detailed tracing
• performance data is accurate
• code compiles successfully
