fix: resolve 6 remaining Playwright e2e test failures on CI

- archive-tab: replace waitForFunction with waitForURL for ?open= intent
  consumption, increase test timeout to 300s for slow rootNavigationState
  init on CI
- launcher-tab: use Control+t on Linux instead of Meta+t to match app's
  keyboard shortcut definitions for non-Mac platforms
- new-workspace: add waitForSidebarHydration to wait for daemon
  connection before checking sidebar rows, add re-navigation fallback
  if app redirects during hydration, increase timeouts
- setup-streaming: use waitForTerminalContent (xterm buffer API) instead
  of fragile .xterm-rows CSS text matching, wait for terminal attachment
  before checking content
