122 day12 part2

// AoC 2015 Day 12 Part 2 — sum numbers, but ignore any OBJECT (and its
// children) containing the value "red" (arrays with "red" still count).
// Statement examples: 6, 4, 0, 6. Ledger: structural JSON walk ← store +
// string-ops (part 1's flat char machine can't see object boundaries).
