🛑 AI review — Sensitive area, extra care recommended

This PR touches critical paths or introduces changes the model cannot judge with sufficient confidence. Review carefully before merging.

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

Summary: Changes in installer templates modify gRPC proxying from plaintext to TLS (grpcs), breaking existing agent communication.

• high installer/templates/front-end.go:74 — Switching agent gRPC endpoints from grpc:// to grpcs:// in the Nginx template forces TLS without providing a fallback or maintaining backwards compatibility for existing deployed agents, resulting in an agent-breaking change.

✅ bugs (gemini-3-flash-lite) — clean

Summary: Nginx template updated to use grpcs for gRPC proxy locations with ssl verification disabled.

No findings.

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

Summary: Diff touches security-critical paths (nginx TLS configuration/installer templates for gRPC proxying).

No findings.

grpcs is needed so tls is executed on the agent manager connections
