fix: settings window close button (and programmatic resize) silently failing

[nov30th]

Summary

The custom close button (✕) in the top-right of the detached Settings window does nothing on Windows. Alt+F4 works.

The same silent failure also affects applySettingsWindowSize — the frontend calls getCurrentWindow().setSize(...) when switching tabs (e.g., widening the window for the Providers tab), and those calls are rejected too.

Root cause

apps/desktop-tauri/src-tauri/capabilities/default.json only scopes its permissions to the main window:

"windows": ["main"],

The detached Settings window is created with label "settings" (see shell/settings_window.rs::SETTINGS_LABEL), so it falls outside the capability's scope. Tauri's IPC permission layer rejects core:window:* calls from it without surfacing an error to JS.

Alt+F4 bypasses this entirely — Windows dispatches WM_CLOSE at the OS level, so the native close path works while the in-app button doesn't. That's the smoking gun for a missing capability scope.

Fix

Add "settings" to the capability's windows array so the existing core:default (which grants close/show/focus/minimize) and core:window:allow-set-size apply to the settings window as well.

- "windows": ["main"],
+ "windows": ["main", "settings"],

No code changes needed — Settings.tsx already calls getCurrentWindow().close() on the ✕ button; it just wasn't permitted.

Test plan

• Rebuild (npm run tauri:dev or tauri:build) — capability files are compiled into the binary, not runtime-loaded.
• Open Settings from the tray → click the ✕ in the top-right → window closes.
• Open Settings on the General tab, switch to Providers → window widens from 496 → 720 logical px (previously silently no-op'd).
• Alt+F4 still closes the window (unchanged).

Hey thanks for the PR, I will check on it and Merge

Thanks for the PR, this was exactly the right fix. The missing settings capability scope explains the close/resize behavior cleanly, and I merged it into main. Appreciate the help.
