### Is there an existing issue for this?

### Describe the bug

Attempting to start a Go AppHost fails when connecting through the backchannel with a timeout error.

### Expected Behavior

The apphost starts up.

### Steps To Reproduce

1. Create a new apphost using `aspire init` and selecting go
2. Run `aspire run` on that apphost, it will timeout on connecting.

### Exceptions (if any)

A log file, no exceptions however.

### Anything else?

Go 1.26

I did test Python as well, and it starts up every time. No matter how many times I try with Go it fails with the same error. So this does seem like its exclusively a problem with Go app hosts.
