{"content":"I'm creating an extremely difficult regex challenge that combines multiple complex pattern types in a single text. This challenge requires matching:\n\n1. Semantic version numbers with pre-release tags and build metadata\n2. ISBN numbers in different formats (10 and 13 digits with various separators)\n3. UUIDs in standard format\n4. MAC addresses in three different separator styles\n5. IPv6 addresses in both full and compressed notations\n\nEach pattern type has its own complex rules, and there are many near-matches and invalid formats that should be excluded.
