fix: build Web image builder stage on native platform#334
Merged
Conversation
The v0.10.6 release CD run failed the Web image build: bun install under QEMU emulation for the linux/arm64 target corrupted extraction of the @biomejs/cli-linux-arm64 tarball (a devDependency never actually invoked by the build script). Since apps/web's build output is architecture-independent static assets, pin the builder stage to --platform=$BUILDPLATFORM so it always runs natively and skips QEMU entirely; only the final caddy runtime stage needs to be multi-arch.

Reviewed changes — pins the Web image builder stage to the native build platform so bun install runs without QEMU emulation on linux/arm64, avoiding a tarball-extraction failure with @biomejs/cli-linux-arm64.
- Pin builder to
--platform=$BUILDPLATFORMinapps/web/Dockerfile— the builder stage produces architecture-independent static assets (tsc -b && vite build), so cross-arch emulation provides no benefit and thebun installstep has been observed to corrupt native-binary tarballs under QEMU. Thecaddy:2-alpineruntime stage remains multi-arch, unchanged.
