⚡ Bolt: [performance improvement] Replace Matcher.replaceAll with literal String.replace in FileNameEvaluation

[RoiSoleil]

💡 What: Replaces pre-compiled Matcher.replaceAll regex substitutions with literal String.replace invocations for \\E\\Q, .*, and \\Q/\\E in FileNameEvaluation.java. Unused Pattern constants are removed.

🎯 Why: In modern JDKs, using String.replace is significantly faster than using a regex matcher when performing literal string replacements, as it entirely avoids regex compilation and evaluation overhead. For the fast-path where characters are not found, it is zero-allocation.

📊 Impact: File name evaluation mapping logic will run much faster and with fewer allocations.

🔬 Measurement: Review application responsiveness during mass file evaluation or rename refactorings. Changes verified with mvn test.
