shell-quote: Quadratic-complexity Denial of Service in `parse()` (CWE-407)

Summary shell-quote's parse finalizes its token list with a reduce that uses Array.prototype.concat as the accumulator. Each prev.concatarg copies the entire growing array, so parse runs in On² in the number of tokens. An unauthenticated attacker who can submit a string to any code path that call...
