Phone Number ExtractorExtract phone numbers from text with international format support.

The extractor uses a flexible regex pattern that matches common phone number formats. The pattern supports optional country code (+1, +44, etc.), area codes with or without parentheses, and digit groups separated by hyphens, dots, or spaces. After extraction, results are filtered to ensure they contain at least 7 digits (removing non-digit characters for counting), which helps eliminate false positives from other number patterns. JavaScript Set is used for deduplication while preserving order of first occurrence.
