ruv 2400216920 fix(cog-person-count): flag untrained-class counts low_confidence (ADR-159 A2)
The count head has 8 classes but count_train_results.json only has
support for classes 0/1 (presence, not multi-occupant counting). An
argmax on classes 2..=7 is out-of-distribution, yet the cog emitted it
as a confident headcount and the crate billed itself a "multi-person
counter".

- Add MAX_TRAINED_CLASS=1, CountPrediction::is_low_confidence() and
  clamped_count().
- person.count events now carry low_confidence + raw_count, downgrade to
  level "warn" when OOD, and clamp the reported count to the trained
  range (no fabricated headcount).
- run.started discloses count_max_trained_class / count_classes.
- Cargo.toml description: "multi-person counter" ->
  "presence detector + (data-gated) person count".

Multi-occupant accuracy stays DATA-GATED (not fabricated).

Failing-on-old test: untrained_class_argmax_is_flagged_low_confidence.
