Build & run (v0 skeleton)

go build ./... && go vet ./... && go test ./...
cp harness.toml.example harness.toml      # then set the key refs
./bin/harness once --dry-run --demo       # intake + plan, no LLM call
HARNESS_LITELLM_KEY=sk-... ./bin/harness once --demo   # MVP demo turn

harness once runs ONE conductor iteration (intake -> model routing -> bounded turn via LiteLLM -> REPORT file) and exits; chain iterations by re-invoking. There is no daemon. Exit codes: 0 ok, 1 config/usage, 2 intake, 4 llm/turn. See harness help.
