/**
 * Print formatted output, honoring GNU printf's format-reuse rules.
 *
 * Supports `%s %c %b %q`, the integer conversions `%d %i %o %u %x %X`,
 * the float conversions `%f %F %e %E %g %G %a %A`, and `%%`, with
 * `- + 0 # (space)` flags, numeric or `*` width/precision, and backslash
 * escapes (including `\u`/`\U`) interpreted once in the same scan. When
 * arguments remain after one pass the format is reused until they are
 * exhausted; a missing argument renders as the empty string / `0`.
 * Integers wrap at 64 bits; `%a` formats at IEEE double precision. The
 * conversion engine itself lives in `format.ts`.
 *
 * With `-v NAME` the formatted text is stored in the shell variable
 * `NAME` (or the array element `NAME[idx]`) instead of written to
 * stdout, matching GNU printf. An unusable `NAME` is rejected before the
 * format runs (status 2); a readonly name or an out-of-range subscript
 * still reports the format's own errors first, then fails with status 1
 * and leaves the variable untouched.
