Summary

  • Slim down Dockerfile.base to only Rust toolchain + WASM tools
  • build-local.sh uses hero_zero:base with automatic fallback to rust:1.93-bookworm
  • WASM step skips tool installs when already present in base image
  • Add make base target to build and push the base image

Impact

  • Cold builds (CI, fresh workspace): ~5-6 min faster
  • Warm builds: ~30s faster (tool detection skip)
  • Zero risk: automatic fallback if base image unavailable

Test plan

  • make base builds and pushes hero_zero:base
  • make dist uses base image (check build output for image name)
  • BUILD_IMAGE=rust:1.93-bookworm make dist works as fallback
  • WASM step skips installs when tools present

Closes #51

- Slim down Dockerfile.base: only Rust toolchain + WASM tools (no Bun,
  no ONNX, no SSH — those are handled by build-local.sh or run on host)
- build-local.sh uses hero_zero:base with automatic fallback to
  rust:1.93-bookworm if base image is unavailable
- WASM step skips tool installs when already present in base image
- Add `make base` target to build and push the base image

Saves ~5-6 min on cold builds (CI, fresh workspace).
Zero impact on warm builds (tools detected and skipped).

#51
