CLAUDE.md describes `npm run check` as "lint + typecheck + test" but it also runs `build`

[Deepam02]

Problem

CLAUDE.md:51 (the Commands section) documents:

npm run check     # lint + typecheck + test — what CI runs

But the actual root package.json script is:

"check": "npm run lint && npm run typecheck && npm run build && npm run test"

The build step is missing from the description, so the doc understates what check (and "what CI runs") actually does.

What done looks like

• Update the comment in CLAUDE.md:51 to reflect the real pipeline, e.g. # lint + typecheck + build + test — what CI runs.
• (Optional) double-check the prose elsewhere in CLAUDE.md/README for the same omission so the docs agree with the script.

Why it's a good first issue

Single-line documentation fix; no code changes, no behavior change. Good for getting familiar with the repo's contributor docs.
