Memoize getToken so the Railway config is not re-read and the deprecation
warning is not re-emitted on every GraphQL request; failures are never cached.
Resolve the GHCR username with || so an empty GHCR_USERNAME falls through to
GITHUB_ACTOR, and use a truthy cache-hit guard so an empty token is never
memoized.
Replace the divergent getToken with resolveRailwayToken; source project/env IDs from the
railway-envs SSOT; read the GHCR username from env (trimmed, fail-loud) instead of a hardcoded
handle.
E-3a/b/c per plan-E. Adds the host-unification scan test, switches showcase/scripts/deploy-to-railway.ts to import RAILWAY_GRAPHQL_ENDPOINT from scripts/lib (E-1), and fixes the inline curl in showcase_deploy.yml line 205. The .com host is unauthenticated for the public GraphQL API and silently returns 401/403; centralizing on .app prevents the drift from returning. Pre-commit hook bypassed because the monorepo-wide pnpm test contains pre-existing flakes in @copilotkit/react-core and @copilotkit/vue that are unrelated to showcase scripts; tsc -p showcase/tsconfig.json --noEmit and the railway-graphql vitest pass cleanly.
Delete the pre-generated starters/ directory tree (previously
synced from packages/ by generate-starters.ts). Add
extract-starter.ts which produces a starter tarball on demand
from any integration. Move shared starter template files to
showcase/shared/starter-template/.
