Optimizations:

• Line 97: Added precompiled PATTERN_PATH_COLON regex pattern to avoid repeated compilation in stripPathInformation() method
• Line 170: Changed from replaceAll() with string regex (which recompiles pattern each time) to using the precompiled pattern - significant performance
  improvement in hot paths
• Line 327: Modernized array creation using method reference String[]::new instead of new String[result.size()]
• Line 423-450: Refactored getTargetVersionString() method to use modern switch expression, reducing from 26 lines with repetitive if-statements to 14 lines -
  much cleaner and more maintainable
• Line 623-627: Simplified getFeaturePaths() to use streams instead of manual list iteration - more functional and readable
• Line 703-709: Improved thread-safety of addTargetDefinitionMap() by making it synchronized and using computeIfAbsent() to eliminate race conditions and
  simplify logic

Impact:

• Reduced regex compilation overhead in path processing
• Better thread safety for cached data
• Improved code readability with modern Java patterns
• No API changes - all improvements are internal
