Frends.AzureBlobStorage.DownloadBlob / 4.1.0

• Added Options.CopyBlob, Options.BlobCopyDir, and Options.DeleteOriginal to support post-download blob copy and source cleanup in Azure Blob Storage.

• Breaking The Connection parameter tab now appears before Options in the task signature, matching the standard parameter order used across all Frends Azure Blob Storage tasks.

• Removed unsupported XML documentation tags to improve compatibility with the Frends task documentation system.

Upgrade instructions (3.x → 4.0)

1. In any process using this task, re-map the Connection and Options parameter tabs — their order in the task configuration UI has swapped. No property values need to change; only the tab order is different.

• Breaking Replaced Source and Destination parameter tabs with unified Input and Options tabs.
• Breaking Input.ActionOnExistingFile replaces Destination.FileExistsOperation; enum value Error renamed to Throw.
• Breaking Input.TargetDirectory replaces Destination.Directory.
• Breaking Options.Encoding replaces Source.Encoding; added UTF8WithBOM value; WINDOWS1252 renamed to Windows1252.
• Breaking Options.OtherEncoding replaces Source.FileEncodingString; separate EnableBOM property removed (use UTF8WithBOM).
• Breaking Result.FilePath replaces Result.FullPath; Result.FileName and Result.Directory removed.

• Added Result.Success (bool) and Result.Error properties.
• Added Options.ThrowErrorOnFailure (default true) and Options.ErrorMessageOnFailure for non-throwing error handling.

Upgrade instructions (2.x → 3.0)

1. Replace Source + Destination parameter tabs with Input + Options.
2. Move Source.ContainerName → Input.ContainerName, Source.BlobName → Input.BlobName.
3. Move Destination.Directory → Input.TargetDirectory, Destination.TargetFileName → Input.TargetFileName.
4. Move Destination.FileExistsOperation → Input.ActionOnExistingFile; change FileExistsAction.Error → FileExistsAction.Throw.
5. Move Source.Encoding → Options.Encoding; change FileEncoding.WINDOWS1252 → FileEncoding.Windows1252; replace EnableBOM = true with FileEncoding.UTF8WithBOM.
6. Move Source.FileEncodingString → Options.OtherEncoding.
7. Replace Result.FullPath → Result.FilePath; remove usages of Result.FileName / Result.Directory.
