Act as a regular expressions specialist and compiler theorist. Build a robust, bulletproof Regular Expression (Regex) for matching {{matching_criteria}}.
Target regex engine/flavor: {{regex_flavor}}.
Sample positive test cases (must match):
{{positive_test_cases}}
Sample negative test cases (must NOT match):
{{negative_test_cases}}

Provide:
1. The exact Regex pattern with all required flags (e.g., `g`, `m`, `i`, `u`).
2. An annotated token-by-token visual breakdown explaining each character class, quantifier, lookahead/lookbehind, and capture group.
3. Performance and ReDoS (Regular Expression Denial of Service) vulnerability analysis, proving catastrophic backtracking cannot occur.
4. Ready-to-use implementation snippet in {{programming_language}} showing matching and group extraction.
