[wrangler] Production deploy failed with Generic Error deploying container application

## Observed symptom Production deploy failed: wrangler "Generic Error" deploying container application ## What happened The manually-triggered [Deploy Production run](https://github.com/DefangLabs/simple-agent-manager/actions/runs/35624569853) on `main` @ `c00b890899fe68580cdc90df8641e3e8e93f87c0` failed in `deploy / Deploy to Cloudflare` at the **Deploy API Worker** step (`wrangler deploy --env production`). The Docker image for the VM-agent container built and pushed successfully (all layers pushed/already-exist, final digest `sha256:dcea583e...`). The failure happens right after, in wrangler's own container-deploy phase: ``` ╭ Deploy a container application deploy changes to your application │ ✘ [ERROR] Generic Error If you think this is a bug then please create an issue at https://github.com/cloudflare/workers-sdk/issues/new/choose Note that there is a newer version of Wrangler av ## Literal error text ``` Generic Error deploying container application ``` ## Environment GitHub issue DefangLabs/simple-agent-manager #48; state=open ## Trigger / context ## What happened The manually-triggered [Deploy Production run](https://github.com/DefangLabs/simple-agent-manager/actions/runs/35624569853) on `main` @ `c00b890899fe68580cdc90df8641e3e8e93f87c0` failed in `deploy / Deploy to Cloudflare` at the **Deploy API Worker** step (`wrangler deploy --env production`).
