functional job still builds after this change
The PR removes the explicit build: true from the functional job, but the setup action's build input defaults to "true" (see .github/actions/setup/action.yaml line 16). Removing build: true without replacing it with build: false leaves the job's behaviour unchanged — pnpm build still runs.
To actually skip the build, build: false needs to be specified explicitly:

**`functional` job still builds after this change**
The PR removes the explicit `build: true` from the `functional` job, but the setup action's `build` input defaults to `"true"` (see `.github/actions/setup/action.yaml` line 16). Removing `build: true` without replacing it with `build: false` leaves the job's behaviour unchanged — `pnpm build` still runs.
To actually skip the build, `build: false` needs to be specified explicitly:
```suggestion
- name: Setup environment
uses: ./.github/actions/setup
with:
build: false
- run: pnpm test:functional
```

The functional job still runs a full pnpm build on every CI run because .github/actions/setup/action.yaml defaults inputs.build to "true" (see its input default and conditional build step). In this change, the with block was removed instead of setting build: false, so behavior remains equivalent to the previous build: true and the intended runtime/cost reduction is not realized for this job.

Summary
build: falseto the setup action in theunit,functional, andlintjobs in.github/workflows/library-ci.ymlbabel-jeston source files; ESLint lintssrc/directly), so the ~5.5-minutepnpm buildthey were running was entirely wasted computeDetails
Eliminates ~16.5 minutes of unnecessary runner compute per Library CI run (5.5 min × 3 jobs). At ~20 runs/day this saves ~330 minutes/day of compute.
The pattern already exists in the other three jobs (
integration,compat,write-mangled-property-names) which correctly usebuild: false+ an explicit conditional build step. This PR brings the remaining jobs in line with that pattern.Confirmed safe by Turbo task definitions:
test:unit— nodependsOntest:functional— nodependsOnlint—dependsOn: [](explicitly empty)Relates to insight: Remove unnecessary pnpm build from Unit, Functional, and Lint jobs
