/**
 * Splits a byte stream into lines with a hard per-line cap.
 *
 * `readline.createInterface` accumulates an unterminated line without bound: a
 * 640 MB newline-free stream threw `RangeError: Invalid string length` from a
 * stream `'data'` listener, which surfaces as an `uncaughtException` rather
 * than an iterator rejection — so the caller's try/catch could not see it and
 * the process died.
 *
 * A line reaching `maxLineChars` with no terminator yields its first
 * `maxLineChars` characters, and the rest of that physical line is discarded up
 * to the next `\n`. `setEncoding` puts a `StringDecoder` in front, so a
 * multi-byte character split across two reads is not corrupted.
