🛑 architecture (gemini-3-flash-lite) — high/critical — please review

Summary: Agent wire protocol and proto contract changes require coordinated agent+server upgrades.

• high agent-manager/protos/agent.proto:86 — Added a new Heartbeat message to the BidirectionalStream oneof. Modifying the wire protocol between the server and deployed agents without backward compatibility mechanisms can break agents in the field.
• medium installer/templates/front-end.go:70 — Changed gRPC timeout configurations from zero (unlimited/keepalive-driven) to 7 days across multiple proxy endpoints. Ensure Nginx and load balancers support this duration safely.

✅ bugs (gemini-3-flash-lite) — clean

Summary: Introduces server and agent heartbeat loops for gRPC bidirectional streams with proper mutex serialization and Nginx timeout updates.

No findings.

🛑 security (gemini-3-flash-lite) — high/critical — please review

Summary: Introduces persistent gRPC heartbeats, modified Nginx proxy timeouts to 7 days, and updates agent/agent-manager gRPC streams.

No findings.
