- Add workspaceTitleGenerator service using Vercel AI SDK - Generate human-readable titles and git-safe branch names - Add sendFirstMessage IPC handler that creates workspace automatically - Add ProjectSelector and FirstMessageInput components for empty state - Update App.tsx to show project selector when no workspace exists - Gracefully fall back to timestamp names if AI generation fails Users can now type a message and hit send to create a workspace with an AI-generated title and branch name based on their message.

The 'name' field is used throughout the backend to compute filesystem paths (e.g., runtime.getWorkspacePath uses metadata.name as the directory). Storing the AI-generated title there would break path resolution. Solution: - Add optional 'displayName' field to WorkspaceMetadata - Store git-safe branch name in 'name' (used for paths) - Store human-readable title in 'displayName' (used for display) - UI prefers displayName over name when rendering This maintains backward compatibility - existing workspaces without displayName continue to work, showing the branch name as before.

FirstMessageInput was using useSendMessageOptions which internally uses useThinking hook, causing 'useThinking must be used within a ThinkingProvider' error in E2E tests when empty state was rendered. Instead, directly use useModelLRU to get the most recent model without requiring context providers. Generated with `cmux`
Instead of showing a project selector dropdown when no workspace is selected, we now: - If only one project exists: Show FirstMessageInput immediately - If multiple projects exist: Show welcome message asking user to select/create workspace via sidebar This is cleaner UX - users already interact with projects via the left sidebar, no need for duplicate selection UI.

Overview
Make workspace creation automatic and invisible. When no workspace exists, typing and sending a message creates one with an AI-generated title and branch name based on the message content.
Changes
Backend
workspaceTitleGenerator.ts- Generates workspace titles and branch names using AIsendFirstMessage- Creates workspace and sends message in one operationFrontend
ProjectSelector- Dropdown for selecting project (auto-hides if single project)FirstMessageInput- Simplified input for first messageApp.tsxto render empty state with project selector + chat inputUser Flow
