Ettore Di Giacinto 1f241fb310 test(distributed): prove the cluster harness with a two-replica baseline
Tasks 4 to 6 built a harness that runs local-ai as real child processes, but
none of it had ever started a process: every spec so far returned inside
argument validation. These two specs are the first to run it against a real
binary, a real Postgres and a real NATS.

Two frontends against one database both see a worker that registered through
only one of them. Every failover spec assumes this, so it is asserted first.

One admin session is minted at frontend 0 and reused for both replicas rather
than registering per frontend. The auth routes share a five-per-minute-per-IP
limiter and all e2e traffic is 127.0.0.1, so a session per frontend would
exhaust the budget as soon as a spec needs a third one. Reuse is sound because
sessions live in the shared Postgres and the harness pins one HMAC secret
across replicas; frontend 1 answering /api/nodes with 200 on a cookie minted at
frontend 0 is what proves it.

The binaries are resolved before SetupInfra so a missing build skips without
first provisioning a database the skip would then have to tear down.
