The unscoped getByRole("button", { name: "Create" }) matched sidebar
"Create a new workspace" buttons from other test suites. Scoping to
message-input-root targets only the Composer submit button.
clickNewWorkspaceButton now completes the full user flow: after
clicking the sidebar button, waits for the /new route, then clicks
the Create button to submit the empty form and trigger workspace
creation + redirect.
assertNewWorkspaceSidebarAndHeader was scanning all sidebar workspace
rows to find the newly created workspace, but would pick up workspaces
from concurrent test suites (e.g. archive-tab). Use the page URL as
source of truth since the app redirects to the new workspace after
creation.
The workspace Stack.Screen was missing a getId callback, causing
expo-router to reuse the same screen instance across workspace
navigations. This left stale params — sidebar switching and new
workspace creation both appeared to navigate but the header stayed
on the old workspace (skeleton for new workspaces).
Adds e2e tests for sidebar workspace switching and new workspace
creation flow (URL, sidebar row, header, single draft tab).
