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.
