Two small per-object-per-frame improvements in the tracker hot path (match_and_update), both bit-identical: - get_stationary_threshold returned a freshly constructed StationaryThresholds (a dataclass plus a list) on every call for any label not in the three known lists - i.e. for common labels like person/dog. The default thresholds are constant and never mutated, so return a shared module-level singleton, as the other three cases already do. - untracked_object_boxes membership used `box not in [list of boxes]` (O(n)); build a set of box tuples for O(1) membership. Boxes are hashable as tuples and output is unchanged. get_stationary_threshold appeared in a live py-spy --gil profile of a camera process_frames worker. Adds tests for the threshold lookups.
