egutierrez 7ec6c4e09f feat(enrichers): cuatro enrichers web — fetch + extract trio (issues 0028, 0028b)
Cada enricher es un par manifest.yaml + run.py en enrichers/<id>/.

1. fetch_webpage (Url, Webpage):
   HTTP GET (requests, fallback urllib) -> html_to_markdown_py_core ->
   sha256(url) -> guarda HTML+MD en cache/<aa>/<sha>.{html,md}. Convierte
   Url -> Webpage con metadata enriquecida (title/status_code/content_type/
   paths/text_length). Crea Domain con relacion BELONGS_TO.

2. extract_domain (Url, Webpage, Email):
   Saca dominio de metadata.url o metadata.address (sin I/O). Crea/conecta
   Domain con BELONGS_TO. Util cuando el usuario quiere ver el dominio
   antes de fetch.

3. extract_links (Webpage):
   Lee metadata.markdown_path -> extract_urls_py_cybersecurity -> dedup ->
   crea nodo Url por enlace + relacion LINKS_TO. Param max_links (50).

4. extract_text_entities (Webpage):
   Lee metadata.markdown_path -> extract_iocs_py_cybersecurity (regex puro,
   sin coste) -> crea entidades por (type, value) tipadas en el registro:
   Email, IPAddress, Domain, FileHash, CryptoWallet, CVE, MACAddress, Phone.
   Cada una con relacion EXTRACTED_FROM al Webpage origen. v1 sin GLiNER/
   GLiREL — esos requieren modelos pre-cargados (futura iteracion).

Probado end-to-end:
  fetch_webpage  https://httpbin.org/html -> 1 Webpage + 1 Domain
  extract_links  -> 2 Url + 2 LINKS_TO
  extract_text_entities -> 8 IoCs (Email, IP*2, CVE, Domain*2, Wallet, Phone)
