Add two complementary features to reduce remote revision cache staleness: 1. Smart local cache: When current system revision matches cached remote revision, force an immediate cache refresh to check for newer revisions. 2. NATS integration: Share cache updates across hosts via NATS pub/sub. Hosts publish revision updates when they fetch new data, and subscribe to receive updates from other hosts. Features include: - Auto-reconnect with infinite retries - Graceful fallback when NATS unavailable - Filtering by flake URL and hostname New CLI flags: --flake.nats.enable --flake.nats.url --flake.nats.subject --flake.nats.credentials-file New NixOS module options under services.prometheus.exporters.nixos.flake.nats Bumps version to 0.3.0.
