saber: manuales cosechados e indice publico pre-construido

- manuales.py cosecha el --help de las herramientas que no traen man page
  (ffuf, sqlmap, suite impacket, netexec, hydra...) y lo escribe como markdown
  en conocimiento/09 - Manuales/. Es la referencia de opciones que la man page
  no da; complementa el cheatsheet de invocaciones comunes.
- indexa.py --publico construye saber-publico.jsonl: glosario + pack de
  conocimiento con los vectores ya calculados, 100% publico y portable.
- busca.py usa ese indice publico como fallback cuando no hay indice personal,
  asi un clon recien hecho consulta al instante sin reindexar nada.
- .gitignore deja pasar saber-publico.jsonl; el personal (saber.jsonl) sigue
  fuera.
- docs/rag.md y el README del pack documentan ambas cosas.
