Iteration 1 — Build caching:
- Backend: cache ~/.nuget/packages keyed on .csproj hashes.
Typical hit: restore drops from ~15s to ~2s (NuGet packages
already cached locally).
- Frontend: cache node_modules + ~/.pnpm-store keyed on
pnpm-lock.yaml. Typical hit: install drops from ~30s to ~3s.
- Concurrency: cancel in-progress CI runs when new push arrives
to the same branch (avoids queue buildup).
Why: On cache hits, CI time drops ~60-70%. Faster feedback for
developers means shorter fix-deploy cycles.
