name: Windows Canary
# Produces an unsigned Windows NSIS installer from main without creating
# a tag, GitHub Release, or auto-updater artifact. The installer is available
# only as a short-lived GitHub Actions artifact for explicit testing.
#
# Design notes vs. signed-macos-canary.yml:
# - No mesh-llm: release-windows doesn't build it.
# - pnpm store restore/save pattern mirrors ci.yml:149-196.
