NTFS file tunneling can restore the original creation time for a
recreated same-named object, which defeated the creation-time
incarnation check and allowed rollback to delete a concurrent
replacement. Replace the platform-specific identity pair with a single
skillPathIdentityProven function:
- Unix: delegates to os.SameFile (inode/dev), ignoring file ID strings
- Windows: compares VolumeSerialNumber:FileIndexHigh:FileIndexLow from
GetFileInformationByHandle, which uniquely identifies the file on the
volume for its lifetime and is unaffected by tunneling
When the file ID cannot be obtained at publish time, identity is not
proven and the auto-delete is refused. Add a regression test that
simulates tunneled creation time and verifies rollback still refuses
the concurrent replacement.
