v4 is bun-first. Run commands directly with Bun on your host machine:
# Install dependencies
bun install --frozen-lockfile
# Run all checks
bun run ok
# Run tests
bun run test
# Build all packages
bun run buildUse Nix as an optional convenience when you want CI-like isolation:
nix develop --command bun install --frozen-lockfile
nix develop --command bun run okMIT
