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.
Extend the chat-ergonomics roadmap with the remaining UX work highlighted by the readiness review.
Document a second pass focused on removing shell glue from canonical CLI handoff flows, making the recommended chat-host profile more obvious without changing 3.x compatibility defaults, and polishing human-mode content reads for cleaner transcripts and copy-paste behavior.
Keep these milestones explicitly workspace-first and scoped to product UX, with CLI-only shortcuts allowed where the SDK and MCP surfaces already provide the structured behavior natively.
