v0.1.0-alpha.9

Release notes — bug fix:

• The window close button (✕) works again. Closing the window from the title bar had stopped working: it did nothing, and the only way to quit was the File → Quit menu item. The ✕ button now closes the window as expected — immediately when there's nothing unsaved, and after the save-or-discard prompt when there is.

Still an early alpha — back up your notes. On Windows, SmartScreen warns on first run because the build is unsigned; that is expected.

Fixed

• Window close (✕) was a no-op because closing goes through window.destroy(), which needs the core:window:allow-destroy permission that core:default does not grant (its window permissions are read-only). Granted it in the main window's capability (src-tauri/capabilities/default.json). The unsaved-changes close guard (installCloseGuard) was already correct; it just couldn't destroy the window. File → Quit was unaffected (native app-quit path).
