<#
.SYNOPSIS
Retrieves refactor definitions from GenXdev preferences based on name patterns.
 
.DESCRIPTION
Searches for and loads refactor definition sets stored in GenXdev preferences.
Each refactor set is stored as a JSON string in a preference with name starting
with 'refactor_set_'. The function deserializes matching sets into objects.
 
.PARAMETER Name
One or more name patterns to match against refactor set names. Patterns are
matched against the portion of the preference name after 'refactor_set_' prefix.
Supports wildcards. If omitted, returns all refactor sets.
 
.EXAMPLE
Get-Refactor -Name "CodeStyle*"
Returns refactor definitions matching pattern "CodeStyle*"
 
.EXAMPLE
refactor "UnitTest"
Uses alias to find refactor definitions containing "UnitTest"
