Subject: [PATCH] Build macOS releases on a supported Apple silicon runner only

The x86_64 job targeted macos-13, which GitHub has retired, so it queued
forever with no runner to pick it up and blocked publish behind it. The
arm64 job used macos-14, which is now deprecated.

Move arm64 to macos-15 and drop Intel entirely: Apple silicon covers every
Mac sold since 2020, and Intel users can build from source. The matrix keeps
its shape so Intel can be restored with a two-line entry.

Follow through in the cask generator, which required both architectures and
would have failed on an arm-only release.

 The cask installs the same notarization-free bundle the release workflow
-publishes for arm64 and Intel. Because the app is ad-hoc signed rather than
+publishes for Apple silicon. Intel Macs get no release asset; build from source
+with `make install` instead. Because the app is ad-hoc signed rather than
 notarized, and Homebrew quarantines every cask download, the cask clears the
 quarantine flag on install. See the
 [tap README](https://github.com/JoshCLWren/homebrew-tap) if you would rather
 handle that yourself with `--no-quarantine`. Building from source avoids the
 question entirely, since a locally built app is never quarantined.
