Seed new sessions locally with a client-generated session ID and create
them in the background, so submitting from the home screen navigates
into the session and renders the prompt echo immediately. The seed
marks initial reads complete until the session.created echo loads
server truth. Creation failure closes the optimistic tab, returns to
the home screen with the prompt restored, and drops the seed. Worktree-
backed creation and command, skill, and shell submissions keep awaiting
creation.
