macOS binaries are not signed.

The `watchman` binaries available for macOS via Homebrew / GitHub Releases are currently distributed without code signing.

```sh
codesign -dvv /opt/homebrew/bin/watchman

Executable=/opt/homebrew/Cellar/watchman/2026.07.27.00_1/bin/watchman

To reduce risks posed by the execution of untrusted binaries, enterprises environments are beginning to enforce aggressive binary authorisation policies that restrict the execution of unsigned code. Having `watchman` signed with one of Meta's Developer ID certificates would allow folks to maintain these policies without disrupting engineers' workflows.
