[eric] e2e+ci: addInitScript in launchApp setting __OPENSWARM_E2E__=true before bundle.js parses so the production-build store-on-window gate fires for specs that drive Redux directly, plus chain selftest-pairwise into verify-all and the e2e workflow so the covering-array math is validated on every CI push
