Subject: [PATCH] ci: add macOS leg to unit-tests matrix (P-21)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Aligns this repo's unit-tests matrix with cascor / data /
cascor-worker / canopy, all of which already include a macOS 3.12
leg. The cross-repo CI audit found data-client, cascor-client, and ml
were ubuntu-only, drifting from the rest of the fleet.

This repo is pure-Python (HTTP / WebSocket client glue) with no
platform-specific code paths, so the macOS leg is a consistency
check — it confirms the package installs and tests pass on macOS,
catching any inadvertent ``os.path.sep`` / fork-only / Linux-glibc
assumption that creeps in via a future refactor.

Refs cross-repo CI audit P-21. ml-side macOS coverage is deferred —
its tests/ exercise bash scripts whose macOS portability isn't yet
validated.
