The editable install of core+server+dev pulls the full scientific Python
stack (SQLAlchemy, aiohttp, pytest, httpx, slowapi, uvicorn[standard],
apscheduler and their transitives) on every CI run. Even with pip cache
the restore + install takes minutes per job — not worth it for a suite
that still runs locally via ``pytest packages/server/tests``.
Kept the frontend svelte-check + build and the non-push Docker image
build. Release workflow no longer has a test gate either (same reason).
Bring the test stage back once we have a prebuilt CI image with deps.
