v1.33.0 — track-aware driver (deterministic §4.0 enforcement)

The CLI/driver now enforces the §4.0 conditional-rigor tracks: a pure parley classify command (deliberation-first, fail-safe) and driver-level routing — fast runs with 1 model-diverse reviewer + collapsed ceremony, explicit standard caps reviewers/rounds/fix-up at 2, and deliberation/absent behave exactly as before (backward-compatible). Hard-rejects fast+auto_implement, fast+strict_gate, and non-solo configs; refutation stays non-optional on every track. Also fixes a pre-existing driver-lock TOCTOU. Designed + reviewed by a real multi-agent Parley (ideas/track-aware-driver; ✅ ×3 over 3 rounds). See CHANGELOG.md.
