knotmirror ingests repo creation event from atproto relay through tap, not from knotstream. Therefore, knotserver will request `sync.requestCrawl` with optional new repo information to notify the repo creation event. Knot will call `sync.requestCrawl` on following cases: - on startup - when `/event` stream has failed - on repo creation (mandatory) Signed-off-by: Seongmin Lee <git@boltless.me>
