Add a Pact consumer test for capabilities.allowed_doc_types ->
NextcloudClient.capabilities() -> GET /ocs/v2.php/cloud/capabilities, pinning
the astrolabe.semantic_search.enabled_doc_types block the search/scan/purge
gates read. Covers the two meaningful provider states: some sources approved
(parsed to the allow-set) and every source disabled (empty frozenset, distinct
from the fail-open None). Produces the nextcloud-mcp-server -> astrolabe pact.
On the provider side (astrolabe's consent-purge pact), register the
"an admin can purge indexed documents" provider state and opt the broker source
into pending pacts, so that authenticated contract reports as pending instead of
failing provider verification until the live-stack auth test-hook is stood up
(ADR-029 phase 4). Already-verified interactions (GET /api/v1/status) stay
blocking.
