Enhance Host Settings Awareness feature

- Added new properties to `HostSettingsManager.Current`:
  `ShowSystemTrayIcon`, `IgnoreShortcutWhenFullscreen`,
  `DisableAnimations`, and `SummonOn` for better extension
  configuration access.
- Improved `SettingsChanged` event handling with examples for
  dynamic UI updates.
- Updated `RaiseItemsChanged` in `HostSettingsPage` to include
  an optional parameter for better UI refresh control.
- Added detailed logging to `OnSettingsChanged` in
  `HostSettingsPage` for improved debugging.
- Updated README with Host Settings Awareness details, examples,
  and links to full documentation.
- Refined helper SDK class descriptions and ensured consistency
  in documentation formatting.
- Maintained backwards compatibility with older hosts.

+##### Host Settings Awareness
+
+Extensions can access the Command Palette's global configuration through the
+`HostSettingsManager` class provided by the Toolkit. This allows extensions to
+read user preferences like the global hotkey, animation settings, and more.
+
+**Reading Current Settings**
+
+Use `HostSettingsManager.Current` to get the current host settings:
+
+```cs
+using Microsoft.CommandPalette.Extensions.Toolkit;
+
+// Get current settings - this is the primary way to access host configuration
+var settings = HostSettingsManager.Current;
+
+// Access individual settings
+var hotkey = settings.Hotkey;                    // e.g., "Win+Alt+Space"
+var disableAnimations = settings.DisableAnimations;
+var singleClick = settings.SingleClickActivates;
+var summonTarget = settings.SummonOn;            // ToMouse, ToPrimary, etc.
+```
+
+Available properties on `HostSettingsManager.Current`:
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `Hotkey` | `string` | Global summon hotkey |
+| `ShowAppDetails` | `bool` | Show app details in UI |
+| `HotkeyGoesHome` | `bool` | Hotkey returns to home page |
+| `BackspaceGoesBack` | `bool` | Backspace navigates back |
+| `SingleClickActivates` | `bool` | Single-click activation |
+| `HighlightSearchOnActivate` | `bool` | Highlight search on activate |
+| `ShowSystemTrayIcon` | `bool` | Show system tray icon |
+| `IgnoreShortcutWhenFullscreen` | `bool` | Ignore hotkey in fullscreen |
+| `DisableAnimations` | `bool` | Animations disabled |
+| `SummonOn` | `SummonTarget` | Monitor positioning behavior |
+
+
+**Responding to Changes (Optional)**
+
+If your extension needs to update when settings change, subscribe to
+`HostSettingsManager.SettingsChanged`:
+
+```cs
+HostSettingsManager.SettingsChanged += () =>
+{
+    // Re-read settings and update your UI
+    var settings = HostSettingsManager.Current;
+    RaiseItemsChanged();
+};
+```
