Privacy check: skip last-commit emails in CI

 ## Unreleased
 
+- The privacy check no longer checks the email addresses on the last commit in CI. Merges made on GitHub, and the test merge GitHub builds for a pull request, carry the account's own email, so every pull request failed. Commit names and messages, every tracked file, and the identity of local commits (pre-commit hook) are still checked.
 - Plain copy never copies DevDriveBackup's password and recovery key folders or key files, also when one of them is itself a selected folder or file. robocopy skips folders only below the one it copies, so such a selection used to be copied as it was, readable recovery keys included. The run now names it as not copied, and names an older copy of a private folder still in the plain copy so it can be deleted.
 - A new source never gets the plain copy or versions folder of a removed source of the same drive. Removed sources keep their folders on the drive, but only connected drives were checked for names in use, so a folder with the same name added while the drive was unplugged wrote into the old copy, and with *Keep deleted* moved the old source's other files aside. A removed folder added again gets its own folders back, unless another source now uses its repository; then it starts with new ones.
 - Before a drive check asks for administrator rights, the window checks whether other accounts can change what it runs (its scripts, `smartctl` and its folder) or rename a folder above them, names those accounts and asks first; a junction or link on the way counts too. The check runs the bundled `smartctl.exe` only when its SHA-256 matches the official 7.5 build and keeps it open, readable only, while it runs; **Install health tool** keeps the installer open in the same way from its checksum check until it has run.
