 - The `PERTURBATION` table is created during database setup by combining all compound, ORF, and CRISPR IDs (no separate CSV file).
 - `PERTURBATION_CONTROL` defines which perturbations are controls (negcon/poscon/empty) and provides human-readable names (e.g., "DMSO" → JCP2022_033924). Note: The ORF table also has a legacy `Metadata_pert_type` column, but PERTURBATION_CONTROL is now the canonical source for all control designations across compound, ORF, and CRISPR modalities.
