[Unreleased]

Added core functions
Updated build file for release
Added new function Invoke-MirRoboCopy to wrap robocopy functionality
Added ShouldProcess support to all public directory-related functions to enable safer operations using -WhatIf and -Confirm:
- Functions updated:
  - Clear-Directory
  - Clear-DirectoryContents
  - Remove-LocalDirectory
  - Remove-RemoteDirectory
  - Remove-DirectoryByType
  - Invoke-MirRoboCopy
Added remote computer availability check using Test-ComputerPing (see WisherTools.Helpers) for functions dealing with remote directories (Remove-RemoteDirectory and Remove-DirectoryByType). These functions now return a FolderDeletionResult indicating if the computer is offline and abort the operation if it is unreachable.
Added enhanced error handling to return detailed failure messages, including when a remote computer is offline or the deletion operation fails.
Created Invoke-RobocopyCommand as a private wrapper for robocopy
Created New-FolderDeletionResult for FolderDeletionResult object creation

Updated functions to implement Invoke-MirRoboCopy for faster and safer directory content clearing using robocopy.
Suppressed nested confirmation prompts in internal function calls by passing -Confirm:$false to internal operations, preventing multiple confirmation requests during execution.
Improved comment-based help for all functions to clearly explain local vs. remote operations, the role of ShouldProcess, and how the remote computer checks are handled.
updated Remove-LocalDirectory and Remove-RemoteDirectory to use new wrapper function New-FolderDeletionResult for FolderDeletionResult object creation
