Subscribe to notifications from holod via the streaming Subscribe RPC. A background receiver thread with its own gRPC connection and tokio runtime pushes received notifications into a fixed-size circular buffer (1024 entries). New commands: - notification start: subscribe to all YANG notifications - notification stop: unsubscribe (buffer contents are kept) - show notifications: print buffered notifications (pager/pipe aware) Notifications are rendered as human-readable one-line summaries: the JSON payload is parsed against the YANG schema (DataOperation::NotificationYang) and all leaf values are flattened into a single 'name=value' line, uniformly for every notification defined in the loaded modules. Ancestor list keys (e.g. the BGP neighbor's remote-address) appear automatically. Entries that fail to parse fall back to a one-line raw JSON dump; the raw format is also available via 'show notifications json'. Cargo.lock: sync yang5 to 0.2 per the earlier Cargo.toml bump.
