.generate_data_subset_condition

Internal helper that translates ARS data-subset metadata into a filter
expression suitable for inclusion in generated R code. Handles comparator
translation, type coercion, and workbook-specific formatting differences.

Analysis Results Standard (ARS), a foundational standard by CDISC
(Clinical Data Interchange Standards Consortium), provides a logical
data model for metadata describing all components to calculate Analysis Results.
<https://www.cdisc.org/standards/foundational/analysis-results-standard>
Using 'siera' package, ARS metadata is ingested (JSON or Excel format),
producing programmes to generate Analysis Results Datasets (ARDs).
