Build and Runtime Config Drift

cluster-178

Build tooling and environment configuration drift causes deployed apps to run with incorrect bundling, stale secrets, or missing Azure/Vercel env vars, leading to broken runtime behavior (read-only public paths, wrong passwords, routing or initialization failures).
