  • 💡 What: Replaced Regex based name conflict resolution with optimized string parsing in NamingUtils.GetNextBestName and NamingUtils.GetNextBestFilename.
  • 🎯 Why: The previous implementation compiled a new Regex for every call, causing significant CPU overhead and memory allocation (approx 9KB per call).
  • 📊 Measured Improvement:
    • Baseline: Mean = 23.98 us, Allocated = 9.09 KB
    • Optimized: Mean = 1.72 us, Allocated = 480 B
    • Result: ~14x speedup and ~95% reduction in memory allocation.

Verified with existing tests (osu.Game.Tests.Utils.NamingUtilsTest) and added a new benchmark (osu.Game.Benchmarks.BenchmarkNamingUtils).
