OpenCrypt 0.2.1

[0.2.1] — 2026-08-01

Fixed

• Installer: PATH refresh reliability. The environment broadcast was
  sent manually via SendMessageTimeout; replaced with Inno Setup's
  native ChangesEnvironment=yes, which reliably notifies running
  applications after install and uninstall.
• Installer: PATH deduplication. EnvAddPath now checks the full
  path list before appending, so re-installs don't grow the PATH
  variable with duplicates.

Changed

• README: documented the headless opc CLI (usage, key auto-detection,
  exit codes, dev entry point in the venv).
