- The hero workspace chip is a selector: no-live-selection states (cold
start, workspace deleted from the sidebar after the list is ready) now
render a "Choose workspace" placeholder (closed-folder icon) instead of
resurrecting the deleted folder name via the session cwd; the cwd-derived
name still bridges the initial list load. Stale pending picks clear when
their workspace leaves a ready list.
- The expanded sidebar wordmark starts a new session (visuals unchanged,
pointer cursor only); the collapsed rail logo keeps its expand toggle.
- The centered hero composer stack gains a 32px foot for visual balance.
