Pull request overview

Adds end-to-end propagation of the --posix-properties-style option so the selected POSIX metadata style (e.g., amlfs) is validated at parse time and persisted into job part plans for execution/resume.

Changes:

• Parse and validate posixPropertiesStyle in rawCopyCmdArgs.toCopyOptions so invalid values fail early and valid values are carried into azcopy.CopyOptions.
• Persist PosixPropertiesStyle into the job part plan header when creating the plan file, so STE uses the intended style during execution.
