[Bug] opencode not available when using msb #228
Description
What happened?
running ./acq run opencode /my/repo/path with backend set to msb (via ./acq backend set msb) results in the sandbox being spun up as expected, but instead of starting opencode I just end up with a root shell in the sandbox.
# whoami
root
# ls -la /home/agent

What did you expect?
running ./acq run opencode /my/repo/path starts opencode as the agent user.
Steps to reproduce
./acq backend set msb

Should be fixed as of #230 and microsandbox 0.6.7. I haven't tagged releases yet, but it's all in
mainin this repo and the patterns repo. Thanks for your patience!
