refactor: eliminate duplicate utility functions by creating shared util package
- Create src/php/util/util.go with shared utilities: - UniqueStrings(): Deduplicates string slices - GetCompiledModules(): Gets built-in PHP modules via php -m - CompareVersions(): Semantic version comparison - Update src/php/supply/supply.go: - Remove duplicate getCompiledModules() function - Remove duplicate uniqueStrings() function - Update all call sites to use util package - Update src/php/extensions/composer/composer.go: - Remove duplicate getCompiledModules() function - Remove duplicate uniqueStrings() function - Remove duplicate compareVersions() method - Update 20+ call sites to use util.CompareVersions() - Update src/php/options/options.go: - Remove duplicate compareVersions() function - Update sortVersions() to use util.CompareVersions() Impact: - Eliminated ~170 lines of duplicate code - All 144 unit tests pass - Consistent behavior across all modules
