VITE_APP_URL (build-editor --app-base, set to app.pcbjam.com in release CI)
turns on a redirect gate in App: home, project overview and mgmt-only paths
bounce to the mgmt app preserving path+search; tool boots, file deep-links,
lib editors and the @local pseudo-scope stay local. Unset (dev/demo) keeps
today's behavior. Policy is a pure helper (lib/redirect.ts) + vitest table.
