Founder Architect agent critical EPERM error

[hnipps]

The Founder Architect agent in the default workflow is not able to read /Users/<username>/.codemachine/claude/.claude.json for some reason. This prevents the agent from creating the architecture doc and therefore the workflow cannot continue.

I have successfully run the workflow once before, without encountering this, and I haven't updated the CLI since.

I'm using Claude Code as the sole engine and have confirmed that Claude Code can read the file when run directly via the claude CLI.
