Contract rev 9 removes the instance CA, client certificates, the peer listener and the trust store fleet-wide. Internal traffic is plaintext HTTP on each service single :8080 listener, so there is no peer identity left to authorize: delete lib/pki, lib/federation, devboot, the per-service database role model and the /api/peers* and /api/instances surfaces, and drop the console Trusted services UI. Config delivery now rides a dedicated ES256 token from lib/configsign rather than mTLS, and the instance fingerprint is derived from a persisted random key and is informational only. main.go also wires the surfaces introduced by the later commits, which this change is what makes possible.
