v1.1.0

Datastore moves to the cluster's system PostgreSQL; the agent is now stateless.

• Build jobs, logs, one-shot job records, the SQL schema cache, and single-use
  upload/pull tokens now persist in the RunOS control plane's system PostgreSQL
  instead of a local SQLite file. The agent discovers that database via a
  control-plane-maintained runos-system-db ConfigMap, self-provisions a runos
  database and role (storing the generated password in a Secret), and migrates
  its cluster_agent_-prefixed schema automatically.
• Self-healing connection: the datastore is reconciled in the background, so the
  agent never crashes if PostgreSQL is briefly unavailable, retries indefinitely,
  and reconnects and re-provisions automatically if the system database is moved
  to a different instance.
• Upload/pull tokens are now hashed at rest (SHA-256); the raw token is never
  stored.
• The agent is stateless: the /data PersistentVolume is gone.
• The binary is now built CGO-free with pure-Go drivers, so the multiarch image
  cross-compiles natively (no QEMU) and release builds are substantially faster.
