[Bug]: Integration tests - `container machine` startup flakes - XPC timeouts.

[jglogan]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

Occurs primarily when running tests in CI. I don't see it very often with local runs:

rm -rf ./test-logs ./test-temp ; make APP_ROOT=./test-data LOG_ROOT=./test-logs PRESERVE_KERNELS=true all test integration

Problem description

We see errors like this:

✘ Test testCreate() recorded an issue at TestCLIMachineCommand.swift:27:6: Caught error: .nonZeroExit(1, "Warning! Running debug build. Performance may be degraded.\n[0/3] [0s]\n[1/3] Fetching image [0s]\n[2/3] Unpacking image [0s]\n[2/3] Unpacking image [1s]\n[2/3] Unpacking image [2s]\n[2/3] Unpacking image [3s]\n[2/3] Unpacking image [4s]\n[2/3] Unpacking image [5s]\n[2/3] Unpacking image [6s]\n[2/3] Unpacking image [7s]\n[2/3] Unpacking image [8s]\n[2/3] Unpacking image [9s]\n[2/3] Unpacking image [10s]\n[2/3] Unpacking image [11s]\n[2/3] Unpacking image [12s]\nError: failed to create container machine (cause: \"internalError: \"XPC timeout for request to com.apple.container.core.machine-apiserver/createMachine\"\")")
━ Test testCreateNameLongestValid() recorded a known issue at TestCLIMachineCommand.swift:45:29: Caught error: .nonZeroExit(1, "Warning! Running debug build. Performance may be degraded.\nError: failed to boot container machine (cause: \"internalError: \"XPC timeout for request to com.apple.container.core.machine-apiserver/bootMachine\"\")")

At present we have testCreateNameLongestValid marked to xfail, but when testCreate fails, the build errors out.

Environment

- OS: 26
- Xcode: 26
- Container: main
