UUID v4 & Time-Sorted UUID v7 Generator

Q: Why are UUID v7 identifiers superior for database primary keys?

UUID v7 embeds a millisecond UNIX timestamp in the first 48 bits, allowing B-tree database indices (PostgreSQL, MySQL) to append records sequentially without index fragmentation.

Generate cryptographically secure RFC 4122 v4 UUIDs and monotonic, database-indexable RFC 9562 v7 UUIDs in bulk.
