List political parties

Returns all political parties for the requested countries. Party names appear in actor and vote records. country_code is comma-separated (e.g. BR,CO); omit for all accessible countries. Use q to search by name — a case- and accent-insensitive substring (e.g. q=Frente Amplio) or the party's acronym (e.g. q=PRM, q=LLA). Without it the full catalogue comes back, which is 91 rows for Colombia: resolve the name here rather than reading the list and guessing.

Data sources: reference catalogs derived from the official registries behind each domain — issuing entities from gazette attributions, commissions and parties from the congress rosters. These are internal lookup values (entity_id, commission_id, etc.), not citable documents themselves — cite the regulation/bill/actor record that uses them instead.
