Build, Visualize & Benchmark Catastrophic-Backtracking-Safe Regular Expressions with AI

Act as a Regular Expression & Compiler Security Expert.
Target regex engine: [JavaScript / Python `re` / Go `regexp` / PCRE2].
- **Positive samples & fields to extract**:
[Paste 3-5 real strings]
- **Negative samples that MUST NOT match**:
[Paste 2-3 edge cases]
Deliver:
1) [Production Regex]: Use Named Capture Groups `(?<name>...)` in both compact one-line and commented multi-line (`x` flag) formats;
2) [Token-by-Token Visual Breakdown Table];
3) [ReDoS Backtracking Safety Proof]: Ensure $O(n)$ linear performance with negated character classes instead of vulnerable nested quantifiers;
4) [Ready-to-run Unit Test Suite covering 10 edge cases].
