'infra single-project' fails when run after `deploy` for agent_runtime

[sushicw]

Problem

When using Agent Runtime (Reasoning Engine), running agents-cli infra single-project after an initial agents-cli deploy does not work as intended.

infra single-project uses terraform, but deploy does not and uses an API instead. This means that when single-project tries to use terraform to update, it doesn't have visibility into the existing reasoning engine resource already created. So, the terraform apply invoked by single-project silently provisions a second Reasoning Engine instance with the same name.

This leads to:

• Observability environment variables being wired to the new (empty) instance.
• The original (serving) instance remaining without observability configuration.

Workarounds

See https://github.com/google/agents-cli/blob/main/skills/google-agents-cli-observability/SKILL.md#order-of-operations-for-agent_runtime-deployments

The short version though: either run single-project before deploy so tracking is properly established, or fix it manually using the above instructions.
