Add multi-round testing capability and granular timing metrics

This PR introduces two improvements to test.py:

1. Add -t option to support multiple test rounds

   • Enables running the model through several consecutive test iterations
   • Provides more comprehensive performance evaluation
   • Available as an advanced option for users needing deeper analysis

2. Separate timing measurements for each test phase

   • Breaks down execution time by testing stage
   • Improves visibility into performance bottlenecks
   • Helps identify specific areas for optimization

These changes enhance both testing capabilities and observability without affecting the default user experience.
