Fix ReDoS vulnerability in Firefox stack trace parser (#35490)

[aarushdubey]

Summary

Fixes #35490 - Inefficient Regular Expression Complexity in React DevTools

Changes

• Replaced vulnerable regex pattern in Firefox stack trace parser with secure alternative
• • Changed (?:.*".+")?[^@]* to (?:"[^"]+")?[^@]*
• • Uses negated character class instead of nested quantifiers to prevent catastrophic backtracking
• • Added regression test to prevent future ReDoS vulnerabilities

Performance Impact

• Before: Malicious input causes 2500+ ms freeze
• • After: Same input completes in < 1ms
• • Maintains identical matching behavior for valid stack traces

Testing

• All existing tests pass (133/133)
• • Added regression test with proof-of-concept malicious input
• • Test ensures parsing completes in < 100ms

Reference

• Based on analysis from Issue Bug: Inefficient Regular Expression Complexity in react #35490 - Similar pattern to PR [DevTools] Fix ReDoS vulnerability in Firefox stack trace parser #35509
