Pull Request Overview

This PR adds debugging functionality to the minifier by tracking and returning the total number of iterations performed during the minification process. This information is displayed in the minsize benchmark output to help identify performance issues.

• Modifies the minifier API to return iteration count alongside the minified code
• Updates the benchmark table format to include an "Iterations" column
• Threads the iteration count through the minification pipeline from peephole optimizations to the final output
