chore: release 1.4.1 (#2447)

## Improvements

* Moved the File Manager breadcrumb into the Contents card header for a
cleaner, more consistent interface.
* Updated the Wireless Transfer section of the User Guide with clearer
instructions.
* Battery status bar indicator no longer changes position when adding or
removing bookmarks.

## Performance

* Optimized path normalization for faster file handling.
* Significantly improved bookmark rendering by removing unnecessary
XPath lookups.
* Optimized dithered rectangle drawing (fillRectDither) using a
byte-aligned rendering implementation, improving display performance on
supported devices.

## Bug Fixes

* Fixed an issue where the Inverted Orientation label was incorrectly
combined with the Color Filter label for Geman localization.
* Fixed excessive ghosting on the X3 cover screen during sleep

 CrossPoint supports sending books from Calibre using the CrossPoint Reader device plugin.
 
-1. Install the plugin in Calibre:
+#### Installing the Plugin in Calibre
 
-   - Head to https://github.com/crosspoint-reader/calibre-plugins/releases to download the latest version of the crosspoint_reader plugin.
+If you don't already have the plugin installed:
 
-   - Download the zip file.
+1. Head to https://github.com/crosspoint-reader/calibre-plugins/releases to download the latest version of the crosspoint_reader plugin.
+2. Download the zip file.
+3. Open Calibre → Preferences → Plugins → Load plugin from file → Select the zip file.
+4. Restart Calibre.
 
-   - Open Calibre → Preferences → Plugins → Load plugin from file → Select the zip file.
+#### Configuring the CrossPoint Plugin in Calibre
+1. In Calibre select Preferences.
+2. In the Preferences dialog select Plugins.
+3. In Plugins search for "crosspoint".
+4. Click on "Customize plugin".
+5. Update the value for "Host" to match the IP for your device.
+6. Leave the other settings as they are.
+7. [optional] Modify the "Upload path" to point to a subfolder other than the root "/" folder. Enter this as a path relative to the root folder. Example: `/mybooks`
+8. Restart Calibre.
 
-2. On the device: File Transfer -> Calibre Wireless, then join a network.

-3. Make sure your computer is on the same Wi-Fi network.
+#### Uploading Books
 
-4. In Calibre, click "Send to device" to transfer books.
+To upload a book using the CrossPoint plugin in Calibre:
+
+1. On the device: File Transfer -> Calibre Wireless, then join a network.
+2. Select one or more books.
+3. Right-click on that selection.
+4. Select "Send to Device" > "Send to main memory"
+
+The CrossPoint plugin will connect to your device, create a folder for the book's author in the root folder (or the folder you configured for the plugin), then copy the book into that folder.
