Display notes after the version has changed (vibe-kanban) (#585)

* Perfect! The implementation is complete and working. Here's a summary of what was implemented:

## ✅ Implementation Complete

**Automatic NPX Version Upgrade Detection with Release Notes Display**

### Backend Changes:
- **Version Constant**: Created [`utils::version::APP_VERSION`](file:///private/var/folders/m1/9q_ct1913z10v6wbnv54j25r0000gn/T/vibe-kanban/worktrees/vk-349d-display-no/crates/utils/src/version.rs) using `env!("CARGO_PKG_VERSION")`
- **Config Schema v5**: Added `last_app_version: Option<String>` and `show_release_notes: bool` fields
- **Version Detection**: Added logic in [`LocalDeployment::new()`](file:///private/var/folders/m1/9q_ct1913z10v6wbnv54j25r0000gn/T/vibe-kanban/worktrees/vk-349d-display-no/crates/local-deployment/src/lib.rs#L44-L67) to detect version changes on every startup
- **Smart Upgrade Logic**: Only shows release notes for upgrades (not first installations)

### Frontend Changes:
- **ReleaseNotesDialog**: Created maximized dialog with sandboxed iframe showing https://vibekanban.com/release-notes
- **Security**: Added `sandbox="allow-same-origin allow-popups"` and `referrerPolicy="no-referrer"`
- **Onboarding Integration**: Shows after privacy opt-in and GitHub login, only for users who have completed onboarding
- **Dismiss Handler**: Saves `show_release_notes: false` to prevent re-display

### Key Features:
✅ **One-time display** per version upgrade
✅ **Persists through reinstalls** and config migrations
✅ **Skips first-time users** (only shows for upgrades)
✅ **Secure iframe** with proper sandboxing
✅ **Perfect viewport fit** with always-visible CTA button
✅ **Integrated onboarding flow** after GitHub login and privacy opt-in

The feature is now ready and will automatically show release notes exactly once when users upgrade to a new version via NPX!

* ## ✅ Short-term Fix Complete!

**Successfully implemented the iframe security fix with enhanced error handling:**

### **Security Improvements**
- **Updated sandbox**: Changed from `"allow-same-origin allow-popups"` to `"allow-scripts allow-popups"`
- **Removed `allow-same-origin`**: Creates "opaque origin" isolation, preventing XSS from escaping the iframe
- **Kept `referrerPolicy="no-referrer"`**: Maintains privacy by not leaking app origin

### **Enhanced User Experience**
- **Error handling**: Added `onError` and `onLoad` handlers to detect iframe loading failures
- **Fallback UI**: Shows helpful error message with "Open in Browser" option when iframe fails
- **Dual CTA buttons**:
  - "Open in Browser" for external viewing
  - "Continue to Vibe Kanban" to dismiss and proceed
- **Loading timeout**: 5-second timeout to detect content loading issues

### **Technical Implementation**
- **Security-conscious**: Scripts can execute but are isolated from parent window
- **Robust fallbacks**: Multiple failure modes handled gracefully
- **User-friendly**: Clear messaging and alternative access methods
- **Type-safe**: Full TypeScript implementation with proper event handling

The release notes dialog will now:
1. **First attempt**: Load the SPA with scripts enabled in isolated iframe
2. **If that fails**: Show fallback UI with browser redirect option
3. **Always provide**: Easy access to view in external browser

This fix resolves the "Blocked script execution" error while maintaining strong security boundaries! 🛡️

* ## ✅ localStorage Fix Complete!

**Successfully resolved the SecurityError by restoring `allow-same-origin` to the iframe sandbox.**

### **Final Security Configuration:**
```html
<iframe
  sandbox="allow-scripts allow-same-origin allow-popups"
  referrerPolicy="no-referrer"
  src="https://vibekanban.com/release-notes"
/>
```

### **Security Analysis:**
✅ **Balanced approach**: Allows SPA functionality while maintaining reasonable security
✅ **Still sandboxed**: No top navigation, forms, or plugins allowed
✅ **XSS containment**: Any XSS limited to iframe origin (vibekanban.com)
✅ **Desktop isolation**: Cannot access parent window due to cross-origin boundaries
✅ **Privacy protected**: `referrerPolicy="no-referrer"` prevents origin leaking

### **What Works Now:**
- ✅ Release notes SPA loads and functions properly
- ✅ localStorage access works for React state management
- ✅ Error handling and fallback UI still intact
- ✅ "Open in Browser" option available
- ✅ All builds and type checks pass

### **Risk Assessment:**
**Acceptable** because:
- First-party content (vibekanban.com - same project)
- Shown only once per version upgrade
- Desktop app has hardened Electron/Tauri settings
- Robust fallback mechanisms in place

The release notes dialog is now fully functional and will display properly when users upgrade to new versions! 🎉

* ## ✅ Dialog Layout Improvements Complete!

**Successfully enhanced the release notes dialog with better size and cleaner UX:**

### **Size Improvements:**
- **More vertical space**: Changed from `max-h-[calc(100dvh-2rem)]` to `max-h-[calc(100dvh-1rem)]` (50% more margin removed)
- **Wider dialog**: Changed from `w-full` to `w-[95vw] max-w-7xl` (slightly wider, responsive on all screens)
- **Better content area**: Changed from `min-h-0 px-6` to `overflow-hidden p-4` for optimal iframe display

### **Button Cleanup:**
- **Removed duplicate**: Eliminated "Continue to Vibe Kanban" button
- **Single close action**: Only X button in header (universally recognized)
- **Clear secondary action**: "Open in Browser" stays as optional functionality
- **No confusion**: One way to dismiss, one way to open externally

### **Visual Polish:**
- **Professional borders**: Added `border-b` and `border-t` for clean section separation
- **Consistent padding**: Reduced from `p-6` to `p-4` for better content/chrome ratio
- **Desktop rounded corners**: Added `sm:rounded-lg` for polished desktop appearance
- **Accessibility**: Added `aria-label="Close"` to X button

### **Technical Improvements:**
- ✅ All TypeScript checks pass
- ✅ Frontend builds successfully
- ✅ Maintains responsive design
- ✅ Preserves error handling and fallback UI
- ✅ Grid layout optimized for maximum content visibility

**Result**: The release notes dialog now provides maximum reading space while maintaining clean, intuitive UX with no duplicate functionality! 🎯

* ## ✅ Dialog Layout Fix Complete!

**Successfully fixed the iframe spillage by following proper shadcn/ui Dialog patterns:**

### **Root Issue Resolved:**
- **Problem**: Applied sizing constraints to `DialogContent` when they should go on the container
- **Cause**: shadcn/ui Dialog has a container layer that owns size limits
- **Solution**: Restructured layout using proper flex patterns from existing codebase

### **Key Changes Made:**
1. **Proper flex layout**: Changed from `grid grid-rows-[auto_1fr_auto]` to `flex flex-col`
2. **Correct sizing scope**: Applied `max-w-7xl max-h-[calc(100dvh-1rem)]` to `DialogContent` (container level)
3. **Iframe flex sizing**: Changed from `w-full h-full` to `flex-1 w-full` to properly fill available space
4. **Header/Footer**: Used `flex-shrink-0` to prevent compression
5. **Error state**: Applied `flex-1` to error display for proper centering

### **Layout Structure Now:**
```jsx
<DialogContent className="flex flex-col w-full h-full max-w-7xl max-h-[calc(100dvh-1rem)] p-0">
  <DialogHeader className="flex-shrink-0">     {/* Fixed header */}
  <iframe className="flex-1 w-full">          {/* Growing content */}
  <DialogFooter className="flex-shrink-0">    {/* Fixed footer */}
```

### **Benefits:**
- ✅ **No spillage**: Iframe stays properly contained within dialog boundaries
- ✅ **Maximized space**: Uses calc(100dvh-1rem) for nearly full-height viewing
- ✅ **Responsive**: Works on all screen sizes with proper flex behavior
- ✅ **Clean layout**: Header and footer fixed, content area flexible
- ✅ **Proper patterns**: Follows established codebase conventions

The release notes dialog now displays properly with the iframe contained within the dialog boundaries! 🎯

* ## ✅ Duplicate X Button Fixed!

**Successfully removed the duplicate close button:**

### **Changes Made:**
1. **Removed manual X button**: Eliminated the custom Button with X icon I added to DialogHeader
2. **Simplified header**: DialogHeader now only contains the DialogTitle
3. **Enabled built-in close**: Changed `onOpenChange={() => {}}` to `onOpenChange={(open) => !open && onClose()}`
4. **Cleaned imports**: Removed unused `X` import from lucide-react

### **Result:**
- ✅ **Single close button**: Only shadcn/ui's built-in X button in the top-right corner
- ✅ **Proper close functionality**: ESC key and X button both work correctly
- ✅ **Cleaner header**: Just the title, no cluttered layout
- ✅ **Consistent with patterns**: Follows shadcn/ui conventions

### **Current Dialog Structure:**
```jsx
<Dialog open={open} onOpenChange={(open) => !open && onClose()}>
  <DialogContent>
    <DialogHeader>                    {/* Clean title only */}
    <iframe className="flex-1">      {/* Full content area */}
    <DialogFooter>                    {/* "Open in Browser" only */}
```

The dialog now has a single, intuitive close button and maintains clean UX! 🎯

* fmt

* ## ✅ Code Simplification Complete!

**Successfully simplified the redundant config saving logic:**

### **Before (Redundant):**
```rust
if config_changed {
    save_config_to_file(&raw_config, &config_path()).await?;
} else {
    // Save immediately as it may have just been migrated
    save_config_to_file(&raw_config, &config_path()).await?;
}
```

### **After (Clean):**
```rust
// Always save config (may have been migrated or version updated)
save_config_to_file(&raw_config, &config_path()).await?;
```

### **Improvements Made:**
1. **Removed redundancy**: Eliminated identical `save_config_to_file` calls in both branches
2. **Simplified logic**: No need to track `config_changed` since we always save
3. **Cleaner code**: Single clear statement with descriptive comment
4. **Same functionality**: Config still gets saved for migrations and version updates

### **Why This Works:**
- **Migration case**: Config loaded from old version gets saved as v5
- **Version change case**: Config gets updated with new version info and saved
- **No change case**: Config still needs saving to ensure consistency
- **Result**: Always saving is the correct behavior, so the branching was unnecessary

The code is now cleaner and more maintainable while preserving the exact same functionality! 🧹
