⚡ Bolt: Optimize DependencyTools string operations

[google-labs-jules]

💡 What: Replaced String.replaceAll with a manual loop using StringBuilder and String.format with string concatenation in DependencyTools.java.
🎯 Why: DependencyTools methods are called frequently during dependency resolution (thousands of times). Regex compilation and String.format overheads accumulate.
📊 Impact: Micro-benchmark showed ~3.6x speedup (from ~536ms to ~147ms for 100k iterations) for these operations. This should reduce CPU usage and allocation rate during resolution.
🔬 Measurement: Created a temporary benchmark test DependencyToolsBenchmarkTest to verify the improvement.
