Package sink implements crawlmanager.Sink: an HTTP push to a Discovery service.

Package source implements crawlmanager.Source: a fixed config list, and a registry-backed lookup (registry.go/dediquery.go).

Package store is catalogcrawler's Postgres-backed crawlmanager.Store: the crawler_index/crawler_queue/crawler_catalog schema and queries ported from the catalog-crawler prototype's own store package (working, reused as-is -- see migrations/).
