Introduces MetaHub — a coordination layer enabling multiple Loopal Hub instances to form a distributed agent cluster with cross-hub communication. MetaHub architecture: - New crate `loopal-meta-hub` with HubRegistry, GlobalRouter, EventAggregator - Hub-to-MetaHub TCP uplink with bidirectional communication - Cross-hub message routing (meta/route), agent spawning (meta/spawn), agent discovery (meta/resolve), and permission relay - Shadow entries for tracking remote agents locally (wait_agent support) - 8 new meta/* IPC protocol methods - CLI: `--meta-hub <addr>` to start MetaHub, `--join-hub <addr>` to connect Execution mode refactoring (3 orthogonal dimensions): - Frontend: `--server` replaces `--headless` (UI form only) - Lifecycle: `--ephemeral` for one-shot tasks (default: persistent) - Cluster: `--join-hub` / `--meta-hub` (independent of above) - LifecycleMode::Interactive→Persistent, ::Task→Ephemeral - Lifecycle passed explicitly via IPC, not inferred from prompt presence Agent tools for cluster awareness: - `ListHubs` tool: discover other hubs in the cluster - `Agent` tool: `target_hub` parameter for cross-hub spawn - Hub dispatch forwards meta/* methods to MetaHub via uplink Testing: 34 unit/integration tests + 3 real-binary e2e cluster tests
- Add Distributed Cluster section with setup instructions - Update CLI reference: --server/--ephemeral replace --headless, add --meta-hub/--join-hub/--hub-name - Add cluster architecture diagram - Update tool list with ListHubs - Add three-dimension execution model table
