Website offers no desktop download for Intel Macs #1349

Description

The website offers no desktop download for Intel Macs, although every release since 0.3.0 ships thinkrail-desktop-darwin-x64.dmg (#894). The macOS tab of the install picker lists only the Apple Silicon .dmg (apps/website/src/installCommands.ts, detail: "Apple Silicon"), the landing hero's Download for Mac always points at thinkrail-desktop-darwin-arm64.dmg without looking at the CPU architecture (apps/website/src/heroDownload.ts), and the promo routes link the same arm64 build (apps/website/src/vibecoding/desktopDownloads.ts). The download analytics map (apps/website/src/analyticsEvents.ts) also knows only the arm64 artifact, so an Intel download would not be counted.

An Intel Mac visitor therefore downloads an app that cannot run on their machine, and has to find the Intel build on the GitHub Releases page by hand.

Steps to reproduce

1. Open https://thinkrail.ai on an Intel Mac (or any browser) and open the install picker → macOS.
2. Look for an Intel download, or click the hero's Download for Mac.

Expected behavior

The macOS tab offers both builds (Apple Silicon and Intel), the hero picks the Intel build when the browser reports an x86 Mac and otherwise keeps a visible link to the other build, and the download analytics recognise thinkrail-desktop-darwin-x64.dmg.

Actual behavior

Only thinkrail-desktop-darwin-arm64.dmg is offered anywhere on the site; the Intel .dmg exists only on GitHub Releases.
