v1.1.1

Added

• Import keys from a file, not only by pasting: the Import tab has a
  "Browse for key file…" button that opens a native file picker
  (.ppk, .pem, .key, .pub, .txt and all files). The main process
  reads the chosen file and feeds it through the same import path as pasted
  material, so both routes behave identically; the name field pre-fills from
  the file name. Files larger than 512 KB are refused.
