+# Generates an electron-updater latest.yml for a Squirrel.Windows build.
+#
+# Squirrel's electron-builder target emits RELEASES + .nupkg + Setup.exe but NO
+# latest.yml. Existing NSIS clients poll latest.yml, so without this file every
+# already-installed NSIS user is silently stranded on the old build and never
+# migrates. This writes the latest.yml that points those clients at the Squirrel
+# Setup.exe (electron-updater runs it with `--updated /S --force-run`, which the
+# migration proof confirmed installs Squirrel and triggers the firstrun cleanup).
