Build a list of subfactor entries with metric codes and threshold groups
build_subfactor_list.RdEach entry covers one subfactor and contains the three-part dot-separated
path, all metric IDs under that subfactor, and the threshold groups derived
from (factor_threshold, evidence_threshold) pairs.
Value
A list of entries, each a list with path (character), codes
(character vector), and groups (list of threshold-group lists).
Details
This function is a convenience wrapper around build_metric_meta_df() kept
for compatibility. Prefer build_metric_meta_df() for pipeline work.
