v0.5.2

Added

• Windows: "Start at login" tray toggle. A new checkbox in the
  tray menu reads and writes the HKCU\…\Run registry key, so
  users can enable or disable auto-start without touching the
  registry manually. Works whether clipboardwire was installed via
  MSI or as a standalone binary.

Fixed

• CI: apt-get update before install. Release and CI workflows
  now refresh the package index before apt-get install, preventing
  transient 404 failures when GitHub runner mirrors go stale.
