Subject: [PATCH] ci: add Windows test job (windows-2025)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a Windows CI job alongside the existing Linux checks.  Runs the full
test suite (without the Linux-only coverage gate) plus typecheck, lint,
doc-sync, build, hygiene, and demo smoke under PowerShell.  Developer
Mode is enabled via registry for symlink support (fs-local tests,
verify-node-next-types).

Per the windows-support RFC transition plan: step (2) — non-required
Windows CI job to observe stability.
