NUID - A highly performant unique identifier generator.

/**
 * `NuidImpl` is the internal implementation backing the public `Nuid`
 * interface exported from `mod.ts`. Generates 22-base-62-character ids:
 * 12-char crypto-random prefix + 10-char base-62 sequence.
 *
 * Output format matches Go `nats-io/nuid` — same alphabet and length —
 * so nuids generated here look the same as nuids generated by Go.
