Detailed Description

128-bit identifier. Two flavors, both well-formed per RFC 9562:

• Generate : version-4 (random) UUID. Use for entity identities. Backed by XorShift128 (fast, not a CSPRNG) - fine for asset ids, not for secrets.
• FromBytes : version-8 (custom) UUID whose payload bits are a deterministic hash of the input. Equal inputs fold to the same id (content addressing); NOT random. The nil id (all-zero, kNilUUID) is reserved for "unset" and is not a valid v4/v8 UUID.
