0.1.4

Added

• Desktop/Notifications: Add independent config.notifications preferences
  for startup, successful reload, transformation, double-copy bypass, and
  plugin-attention notifications without hiding failures or tray status.
• Packaging/Flatpak: Add one offline Flatpak containing the desktop app and
  sandboxed CLI, GitHub Release bundles with checksums and provenance, and a
  signed shared update repository at flatpak.jag-k.dev. Adapt autostart and
  tray D-Bus registration to the Flatpak sandbox.
• Packaging/Nix: Add a project flake for Linux and macOS app/CLI builds,
  native macOS .app bundles, cross-platform CI, and prebuilt outputs in the
  public jag-k Cachix cache. Keep Intel macOS on the maintained
  nixpkgs-26.05-darwin branch.

Changed

• Documentation: Organize installation by operating system, separate
  package-manager and direct-download options, distinguish GUI and CLI
  artifacts, and document Flatpak sandbox behavior, explicit CLI invocation,
  Nix application paths, and Cachix setup.
