#5906 feat(desktop): create blank projects from Superset

What & why

Superset can clone a repository, open an existing folder, or start from a template, but it cannot create a blank project for someone starting an app from scratch.

This adds a first-class Create new project action to the new-workspace picker, project menus, command palette, legacy workspace flow, and onboarding. The new modal creates a named folder, initializes a Git repository on main with an initial commit, registers the project, and makes it available for workspace creation without leaving Superset. It uses the existing host-service empty-project mode and adds the equivalent v1 desktop path.

How I tested it

• bun run lint — passed with no warnings
• bun run typecheck — 35/35 tasks passed
• cd apps/desktop && bun test src/renderer/stores/add-repository-modal.test.ts — 2/2 passed
• cd packages/host-service && bun test test/integration/project-setup.integration.test.ts — 8/8 passed
• End-to-end in the signed-in desktop app from this managed worktree at renderer http://localhost:3085: New Workspace → project picker → Create new project → enter name/location → Create project → select No agent → create workspace. Verified the resulting folder is a Git repository on main with an initial commit and no remote, and that Superset created and opened the workspace.

Summary by cubic

Adds a “Create new project” flow to the desktop app so users can start from a blank folder without leaving Superset. Creates a named directory, initializes a Git repo on main with an initial commit, registers the project, and returns users to workspace creation with the project selected.

• New Features

  • New EmptyProjectModal to name a project and pick a location, with browse, progress, and error toasts.
  • Entry points in command palette, dashboard sidebar menus, workspace sidebar footer, new workspace picker, and an onboarding card.
  • v1 and v2 support: uses electronTrpc.projects.createEmptyRepo and host-service project.create (empty mode); invalidates projects.getRecents and finalizes setup.
  • Store and flow updates: adds empty-project via useOpenEmptyProjectModal, ensures only one add-project modal at a time, and workspace/onboarding flows preselect the newly created project.

• Refactors

  • Centralized v1 creation error handling with runCreate and onError passthrough in useCreateV1Project; unified pending state with createEmptyRepo.

Summary by CodeRabbit

• New Features
  • Added “Create new project” (empty project) actions across the dashboard, workspace sidebar, command palette, and onboarding.

• Bug Fixes
  • Improved completion, error, and cancellation handling in the empty project flow (including clearer failure toasts and safer close behavior).
• Tests
  • Added coverage for opening, resolving success, and canceling the empty-project modal/store flow.
