pose_v1 has no confidence head, so infer() emits a constant 0.185 per
frame. The config default_min_confidence was 0.3 and the runtime gates
on confidence >= min_confidence, so a default install silently emitted
ZERO pose.frame events while health reported healthy.
- Add inference::MODEL_TYPICAL_CONFIDENCE (0.185, the validation PCK@50)
as the single published per-frame confidence.
- Pin default_min_confidence() to MODEL_TYPICAL_CONFIDENCE so a default
install clears its own gate and emits.
- Warn at run.started when min_confidence exceeds the model typical
confidence (disclosed, not silent); document the trade-off in the
config field, the JSON schema, and inference.rs.
Failing-on-old test: default_config_emits_frames_with_real_model
(with old 0.3 it panics: "default install would emit zero pose.frame
events").
