Build a workspace switcher navigation with Tailwind CSS: an app bar whose left side is a dropdown showing the current workspace (avatar, name, plan) with a searchable list of other workspaces underneath, each with a checkmark when active. Add a 'create workspace' row at the list bottom, keep the main nav links beside the switcher, and support keyboard navigation through the list.
