Extractores nuevos en python/functions/cybersecurity/: - extract_ip_addresses (IPv4 + IPv6 con validacion ipaddress) - extract_emails (RFC 5322 simplificado) - extract_domains (FQDNs con TLD valido, lista estatica) - extract_file_hashes (MD5/SHA1/SHA256/SHA512, algoritmo por longitud) - extract_crypto_wallets (BTC legacy + bech32, ETH 0x+40hex) - extract_cve_ids (CVE-YYYY-NNNN+) - extract_mac_addresses (xx:xx:xx + xx-xx-xx, separador uniforme) - extract_phone_numbers (E.164 + ES local 9 digitos) Pipeline: - extract_iocs corre todos, deduplica spans contenidos. Mantiene purity:pure (kind:function con uses_functions no vacio) porque la regla del registry exige que los pipelines sean impuros. Todas devuelven list[dict] con value/start/end/type para que el caller (issues 0038-0040) pueda reconciliar offsets con spans NER sin reparsing.

| extract_file_hashes | function | py | cybersecurity | 1.0.0 | pure | def extract_file_hashes(text: str) -> list[dict] | Extrae hashes MD5/SHA1/SHA256/SHA512 de un texto, con offsets y algoritmo deducido por longitud (32, 40, 64 o 128 hex). Util para extraer IoCs de reportes de threat intelligence. |

Notas
Detecta solo longitudes canonicas (32/40/64/128 hex). Una secuencia hex de 50 caracteres se ignora. Word-boundary \b evita matchear sub-strings de hex mas largo. ETH wallets (0x + 40 hex = 42 chars totales) NO matchean este extractor por el \b y la ausencia del prefijo 0x en este patron — el pipeline extract_iocs deduplica overlaps si los hubiera.
