feat: funciones Python infra y tipos Python (core, datascience, infra)

Infra: cache_to_file, cache_to_sqlite, http_download_file, http_get_json,
http_post_json, read_file_with_encoding, safe_extract_zip, scan_directory,
setup_logger, normalize_zip_filenames.
Tipos: 30+ tipos core (agent_action, context, task, message, parse_result...),
6 tipos datascience (entity_candidate, extraction_result...), 2 tipos infra.
