Replace the legacy repository tab bar with a compact workspace navigation that groups primary views and exposes a dedicated "Repositories" action. The repository list is shown only when the repository view is active and supports per-repo selection and closing. Also add a Repositories open handler in the app to select the active repo or prompt to choose a repository folder when none is available. - Introduce top-level navigation (Dashboard, PRs, Issues, Repositories) - Add onOpenRepositories hook and app logic to select or choose repo - Update icons, styles, and accessibility attributes for the nav
