The nitro server build re-bundles the whole dep tree (`noExternals: true`), so every React package shipping a `"use client"` banner earns a MODULE_LEVEL_DIRECTIVE warning — ~150 locally, ~800 in CI — which buries the warnings worth reading. Ignoring the banner is correct rather than papered over: this bundle is the Bun/Nitro server, not an RSC module graph, and TanStack Start splits client from server with its own transform, so nothing downstream consults it. Supplying `onwarn` replaces nitro's own handler, so its three filters (CIRCULAR_DEPENDENCY, EVAL, "Unsupported source map comment") are restated. Verified: `bun run build` drops from 148 such lines to 0 with no other log delta; `tsc --noEmit` and `biome check` clean.
