Add mode parameter to upload_file() that sets permissions atomically via SFTP before writing content. All secret files (passwords, keys, .mylogin.cnf) now use mode=0o600. Remove separate change_permissions_to_root() calls that left a readable window. Closes #90 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
