Fix move duplicate handling with hash verification

 - In `copy` mode, source files remain in the UNC path
 - In `move` mode, the program copies first and then removes the source file
+- In `move` mode, if a duplicate is detected, the source file is removed only after hash/content verification succeeds
 - The generic file rule never overwrites an existing target file when a conflict is detected
 - The archive rule only handles `.tar.gz`
