Relay interruption recovery

• Preserve an in-flight MCP tool call across a brief daemon WebSocket interruption instead of converting every transient proxy or network reset into an immediate cancellation. The Worker now detaches pending calls for a bounded 30-second grace period and rebinds them only when the same local daemon process instance completes the full authenticated readiness probe on its replacement socket.
• Keep the local operation running during that grace period and queue a completed result until the relay is ready again. Before ready_ack, the Worker sends an authoritative resume_calls set so the runtime cancels work whose client disappeared during the outage; results are replayed only for same-instance calls that still have a receiver. A different daemon instance cannot claim them, and an unrecovered outage cancels ordinary calls and process trees when the grace period expires.
• Add deterministic registry/runtime regressions and a real Worker/OAuth/MCP fault-injection test that starts a tool call, forcibly drops the daemon WebSocket, reconnects the same daemon instance, and proves the original HTTP request completes. Expose the bounded pending_calls.detached count for diagnosis, require a validated ephemeral daemon instance identifier in the current-version hello contract, and update architecture, logging, operations, audit, and multi-account documentation.
