Minor Changes

• #26 3c80dd7 - Added mode: 'auto': the question runs System 1 first and escalates exactly once to System 2 when the answer's confidence falls below autoModeThreshold (default 0.7; for noul() the confidence equivalent is max(noul, 1 − noul)). The escalated answer is returned as-is even at low confidence — one deliberate pass, never a loop. Confident System 1 answers complete without touching System 2, so the fast path stays in the milliseconds.

• #26 3c80dd7 - Added global debug logging: debug: true on any question (both modes) logs the internals to stderr — the prompt, the wire request body, the endpoint, raw responses with their HTTP status, every retry with its reason and backoff, and in System 2 the model's reasoning text and each structured-rejection reason.

• #26 3c80dd7 - Implement System 2 mode (mode: 'system2') for choice(), score() and noul(): the model deliberates and answers a minimal structured object — one integer 0..10 rating per candidate — and the same answer shapes as System 1 come out of it (winner = argmax, distribution = normalized ratings, same entropy confidence). Requests use response_format with a strict ratings schema, temperature: 0, no default token budget, and a parse-validate-retry fallback that feeds rejection reasons back to the model so engines with broken or missing structured-output support still work. Adds the thinking question option (valid in 'system2'/'auto' mode; false sends reasoning_effort: 'none') and the mode-partitioned question types: Question, ScoreQuestion and NoulQuestion switch from interfaces to unions over mode, so thinking set with mode: 'system1' no longer compiles — breaking for consumers extending those types with interface X extends ... (allowed by semver at 0.x).
