General
- Completed the official rebranding from Calcpad to CalcpadCE.
CLI

- Introduced automatic language selection.
Windows
- The installer now automatically prompts to download and install the required .NET runtime if it is missing.
- Added the ability to select the application language directly during installation.
- Released a portable version.
- Swapped the active filename and the application name in the window title bar to prioritize the filename for better visibility.
- Added the command-line interface (CLI) executable.
Linux
- Released .deb, .rpm, and portable packages for both x86 and ARM64 (including Raspberry Pi) architectures.
- Added dotnet-runtime-10.0 as a package dependency so it installs automatically if missing.
