## Summary
- Add a native notification that appears when a chat response completes
while the Dyad app window is not focused
- Controlled by a new setting "Show notification when chat completes" in
Workflow Settings
- Enabled by default for a seamless notification experience

## Implementation
- Added `enableChatCompletionNotifications` setting to
UserSettingsSchema (default: true)
- Added `isWindowFocused` IPC contract and handler to check window focus
state from main process
- Added notification logic to `useStreamChat`'s `onEnd` callback using
the Web Notification API
- Created `ChatCompletionNotificationSwitch` component for the settings
toggle
- Added the toggle to the Workflow Settings section in the Settings page

## Test plan
1. Start the app and enable notifications in Workflow Settings (enabled
by default)
2. Start a chat and switch focus to another application
3. Wait for the chat response to complete
4. Verify a native notification appears saying "Chat response completed"
5. When Dyad is focused, verify no notification appears
6. Disable the setting and verify notifications stop appearing

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Mostly additive UI/renderer changes with an optional IPC payload
field; main risk is runtime differences around `Notification`
permissions/focus detection across platforms.
> 
> **Overview**
> Adds an opt-in Workflow Settings toggle
(`enableChatCompletionNotifications`) that requests Web Notification
permission when enabled.
> 
> When a chat stream ends, the renderer now conditionally fires a native
`Notification` if the setting is enabled, permission is granted, and the
window is not focused, using the app name as the title and a truncated
`chatSummary`/chat title as the body.
> 
> Extends the `ChatResponseEnd` IPC payload with optional `chatSummary`
and populates it from both the standard stream handler and the
local-agent handler so the renderer can display richer completion
notifications.

## Summary by cubic
Adds a native desktop notification when a chat response completes while
Dyad isn’t focused, controlled by a new Workflow Settings toggle enabled
by default. Helps you notice finished replies while multitasking.

- **New Features**
  - New setting: “Show notification when chat completes” (default on).
- Requests notification permission when you enable it; notifications
show only if permission is granted.
- Sends a notification via the Web Notification API when the window
isn’t focused (document.hasFocus), using the app name as the title and
the chat summary (or chat title) as the body.
