13b58aeaa9 Swiping to close the sidebar (#678)
* enabled drag gesture to close the sidebar view

* removed extraneous onChanged block

* Fix sidebar swipe gestures to work with ScrollView

Improvements:
- Use simultaneousGesture() instead of gesture() to work alongside ScrollView
- Add horizontal-only detection (width > height * 1.5) to prevent interfering with vertical scrolling
- Add visual feedback during drag with sidebarDragOffset updates
- Add 20pt right edge zone for easier swipe-to-open activation (iOS-native behavior)
- Lower threshold for edge swipe (-50pt instead of -100pt)

Both swipe-to-open and swipe-to-close now work reliably:
- Swipe left from anywhere (or from right edge) to open sidebar
- Swipe right on sidebar to close it
- Vertical scrolling unaffected

* Fix sidebar drag offset direction

Changed offset calculation from:
  showSidebar ? -dragOffset : width - dragOffset
To:
  showSidebar ? dragOffset : width + dragOffset

This fixes the issue where dragging right to close the sidebar would
make it fly to the left side of the screen before closing.

Now the sidebar correctly follows the finger during drag:
- When closing: moves right (toward off-screen)
- When opening: moves left (toward on-screen)

* Optimize sidebar drag performance for smooth 60fps

Performance improvements:
- Remove .animation() modifier that was conflicting with drag updates
- Use Transaction with disablesAnimations during drag for instant updates
- Throttle state updates to only fire when offset changes >2pt
- Always render sidebar (avoid conditional view creation overhead)
- Only animate on gesture end, not during drag

This eliminates the lag/jank during swipe by ensuring:
1. No animation conflicts during manual drag
2. Direct offset updates follow finger immediately
3. Stable view hierarchy (no conditional rendering)
4. Reduced state update frequency

The sidebar now feels buttery smooth at 60fps.
