Pull Request Overview

This PR refactors the minifier's peephole optimization code by inlining statement methods for better performance and code organization. The refactoring changes method signatures from returning Option<Statement> to directly mutating the statement in place.

  • Consolidates dead code removal logic into individual statement type methods
  • Eliminates the central remove_dead_code_exit_statement dispatcher method
  • Changes method signatures to take &mut Statement and mutate in place rather than returning new statements
