v0.1.0

Added

• UUID type as [16]byte value type with Nil and Max constants
• UUID generation: NewV3 (MD5), NewV4 (random), NewV5 (SHA-1), NewV7 (timestamp+random), NewV8 (custom)
• Generator type with per-instance V7 monotonicity (RFC 9562 Method 3)
• Predefined namespace UUIDs: NamespaceDNS, NamespaceURL, NamespaceOID, NamespaceX500
• Parse (strict 36-char hyphenated) and ParseLenient (URN, braced, compact forms)
• MustParse for package-level constants
• FromBytes constructor from byte slices
• String and URN formatting methods
• Version, Variant, IsNil, Bytes, Time, Compare accessors
• encoding.TextMarshaler / TextUnmarshaler for JSON support
• encoding.BinaryMarshaler / BinaryUnmarshaler for binary protocols
• encoding.TextAppender / BinaryAppender (Go 1.24) for zero-alloc formatting
• database/sql.Scanner and driver.Valuer for SQL support
• hash.Cloner optimization for V3/V5 namespace hash states
• Pool type with NewV4 and NewV7 for amortized crypto/rand overhead
• NewV4Batch(n) and Generator.NewV7Batch(n) for bulk UUID generation
• Zero-alloc hot paths for NewV4, NewV7, Pool.NewV4, Pool.NewV7, Parse, MarshalText, UnmarshalText
• 100% test coverage including fuzz tests
