assert_eq!(escape_regex("a+b"), "a\\+b");
assert!(is_valid_regex(r"\d+"));

Scope

• lightweight wrappers around the mature regex crate
• simple validation, matching, extraction, and replacement helpers
• string-oriented utilities that stay small and predictable

Non-Goals

• regex engine implementation
• parser generators
• validation frameworks
• security sandboxing
