Make the human workspace read commands easier to use in chat transcripts and shell pipelines by adding CLI-only --content-only to workspace file read and workspace disk read.
Keep JSON, SDK, and MCP behavior unchanged while fixing the default human rendering so content without a trailing newline is cleanly separated from the summary footer.
Update the 3.9.0 docs and roadmap status, and add CLI regression coverage plus a real guest-backed smoke for live and stopped-disk reads.
