Pull Request Overview

This PR refactors the minifier API by introducing new .minify() and .dce() methods to replace the existing .build() method, and implements dead code elimination (DCE) to run in a loop for better optimization. The changes improve the minifier's API clarity and enhance dead code elimination effectiveness.

Key changes:

• Replace .build() method calls with .minify() across the codebase
• Add .dce() method for dead code elimination only
• Implement loop-based DCE execution with iteration tracking
