New decnet/rpki/ module mirrors decnet/asn/ shape. Validator ABC, lazy singleton factory (DECNET_RPKI_PROVIDER=ripestat default), paths.py with DECNET_RPKI_ROOT override. RipeStatValidator stub returns 'unknown' unconditionally — HTTP wired in next commit. enrich_rpki(ip, asn) -> (status, source) | (None, None); short-circuits on DECNET_RPKI_ENABLED=false or asn=None.

"""RPKI validity enrichment — maps (IP, ASN) pairs to route origin validity.

Public surface:
|

* :func:`enrich_rpki` — takes an IP string and ASN int, returns
|
|
``(rpki_status, provider_name)`` or ``(None, None)``.
|

Validator selection goes through :func:`~decnet.rpki.factory.get_validator`
|
|
(env ``DECNET_RPKI_PROVIDER``, default ``ripestat``). Direct imports of
|
|
concrete validators are forbidden — mirrors the ``get_bus`` /

``get_repository`` rule.
