/**
* Generate a CUID2 string.
*
* CUID2 is a secure, collision-resistant identifier that hashes multiple
* entropy sources using SHA3-512. Unlike time-ordered IDs (ULID, UUID v7),
* CUID2 prevents enumeration attacks by making IDs non-predictable.
*
* Note: CUID2 does not provide toBytes/fromBytes because it is a string-native
* format with no canonical binary representation (unlike UUID's 16-byte format).
*
* @example
* ```ts
* import { cuid2 } from 'uniku/cuid2'
*
* const id = cuid2()
* // => "pfh0haxfpzowht3oi213cqos"
*
* // Custom length
* const shortId = cuid2({ length: 10 })
* // => "tz4a98xxat"
*
* // Validation (type guard)
* const maybeId: unknown = getUserInput()
* if (cuid2.isValid(maybeId)) {
*   console.log(maybeId.length) // TypeScript knows maybeId is string
* }
* ```
