fix: refine sidebar folder rows

 Tauri setup keeps launch-time filesystem and subprocess work off the window creation critical path. Legacy `~/Laputa` housekeeping and the initial persisted-vault MCP bridge sync run on named background threads, so large legacy vaults, stale active-vault paths, or slow process startup cannot beachball the macOS app before React mounts. React still resyncs the bridge from `useVaultSwitcher` after the persisted selection loads, and no selected vault stops the bridge. The HTML bootstrap also installs a Tauri-only one-shot watchdog: React reports readiness from an effect after the root commits, and if that readiness signal never arrives the WebView reloads once instead of leaving macOS users in an inert rendered shell.
 
 Linux uses custom React-rendered window chrome instead of the native Tauri menu bar. `setup_linux_window_chrome()` drops server-side decorations on the main window, `openNoteInNewWindow()` does the same for detached note windows, and `LinuxTitlebar`/`LinuxMenuButton` route both window controls and menu actions back through the same shared command pipeline that the desktop native menus use. The native app menu keeps macOS-only Services/Hide entries off Windows and Linux, while cross-platform custom items such as Check for Updates emit Tolaria command IDs and show visible updater feedback.
-When Tolaria is launched from a Linux AppImage, `run()` also applies AppImage-only WebKitGTK startup safeguards without changing native package installs. It injects `WEBKIT_DISABLE_DMABUF_RENDERER=1` and `WEBKIT_DISABLE_COMPOSITING_MODE=1` independently unless the user already set either variable, and on Wayland sessions it re-execs once with the first available system `libwayland-client.so` in `LD_PRELOAD` when the user has not provided their own preload. The rendering overrides keep AppImage WebViews from blanking after accelerated compositing/DMA-BUF failures, while the re-exec addresses AppImage library-order failures that can surface as `Could not create default EGL display: EGL_BAD_PARAMETER` before GTK/WebKit create the display.

It injects `WEBKIT_DISABLE_DMABUF_RENDERER=1` and `WEBKIT_DISABLE_COMPOSITING_MODE=1` independently unless the user already set either variable, and on Wayland sessions it re-execs once with the first architecture-matching system `libwayland-client.so` in `LD_PRELOAD` when the user has not provided their own preload. The candidate order prefers Fedora-style `lib64` and Debian-style `x86_64-linux-gnu` paths before generic `/usr/lib`, and the ELF header is checked so a 64-bit Tolaria process does not retry with a 32-bit Wayland client library. The rendering overrides keep AppImage WebViews from blanking after accelerated compositing/DMA-BUF failures, while the re-exec addresses AppImage library-order failures that can surface as `Could not create default EGL display: EGL_BAD_PARAMETER` before GTK/WebKit create the display.
