mssql-js: neither `yarn lint` nor `yarn format:check` runs in CI

Describe the bug

The repo checklist for mssql-js lists yarn lint and yarn format:check, but neither runs in CI. Both scripts exist in mssql-js/package.json; CI just never invokes them.

.pipeline/scripts/containerized-js-build.sh (the only place JS is built in CI):

cd mssql-js
yarn install
yarn build
ls lib/generated
# echo "Check for formatting"
# yarn format:check      # <-- commented out, line 18
echo "Compiling Typescript files"
yarn buildapi

.pipeline/scripts/containerized-js-test.sh runs only yarn testci. So:

format:check being commented out is at least visible in the diff. lint is the quieter gap: it appears in no pipeline script at all, so eslint . --ext .ts,.js --max-warnings=0 is effectively unenforced despite --max-warnings=0 implying it is a gate.

Steps to reproduce

1. grep -rn "format:check\|lint" .pipeline/scripts/
2. Only hit is the commented-out line 18 of containerized-js-build.sh.
3. Confirm both scripts are defined in mssql-js/package.json.

Expected behavior

Prettier and ESLint are enforced on PR builds, matching the documented contributor checklist — or the checklist is amended to say they are local-only.

Actual behavior

Neither runs. TypeScript/JS formatting and lint regressions can land without CI objecting.

Additional context

Found while validating #264 (a Rust-only change — all 14 changed files are .rs, zero JS surface). Not caused by that PR and not a blocker for it; filing so it is not lost.

Note there is a plausible reason format:check was disabled rather than merely forgotten — it may have been failing on generated output, since yarn build writes into lib/generated before the check would run, and the format:check glob "lib/**/*.ts" covers that directory. If so, the fix is likely to scope the glob away from generated files rather than to simply uncomment the line. lint has no such excuse.

Whoever picks this up should re-enable the two checks in one PR and fix whatever they surface, rather than uncommenting blindly.

Read mssql-js/package.json and .pipeline/scripts/containerized-js-build.sh and containerized-js-test.sh, then run the listed build, format, lint, and test commands locally. Check how generated files under lib/generated affect format:check; done means PR CI runs the intended checks and passes without allowing formatting or lint regressions.
