[Bug]: model generated JSON snippet exceeds output context length

[abrichr]

Describe the bug

 python -m openadapt.replay SegmentReplayStrategy "replay verbatim"

This happens when there are too many segments due to a lack of filtering, e.g.

('```json\n'                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      14:20:57 [36/95455]

For now we will focus on reducing the number of segments per prompt in upstream logic.

[abrichr]

A regression was introduced in #679 in openadapt/adapters/ultralytics.py.

Before:

    conf: float = 0.4,
    iou: float = 0.9,

After:

    # threshold below which boxes will be filtered out
    conf: float = 0,
    # discards all overlapping boxes with IoU > iou_threshold
    iou: float = 0.05,

[abrichr]

The regression has been fixed in #758 but the issue will crop up again for lower NMS threshold values.
