Diffy can now ship native Windows x86-64 per-user NSIS installers and Linux x86-64 AppImages alongside the existing macOS beta. Add native settings paths, terminal forwarding to the running app, platform-specific editor/terminal/file-manager launch, and signed updates with the existing public key and macOS update endpoint.

The site shows $14.99 during beta with $24.99 crossed out, supports one Dodo checkout for every platform, and provides shared post-purchase delivery instructions. The homepage keeps “build for free”; its installation link and yellow beta announcement are removed. Windows/Linux downloads remain gated until their release assets are published and verified.

Validation:

• macOS, Windows, and Linux CI pass functional tests and Clippy; macOS/Linux also run the full UI suites.
• Windows/Linux native startup presents a real frame. Their packaged installations pass CLI Git access, preference preservation, and signed update/relaunch checks; Windows also exercises reinstalling over an existing installation.
• The macOS release is Developer ID signed, notarized, stapled, and passes the real signed-archive update/relaunch test.
• Both site checkout configurations pass. Native packages have matching version, source-tree provenance, and checksums; updater signatures are assembled locally with the existing key.

Windows/Linux remain alphas pending broader hardware testing. Windows installers have no publisher signature; Linux initially targets Ubuntu 24.04+ with Vulkan and X11/Wayland. Release publication and enabling the new website downloads are separate final steps.
