Run build check on push to main

Reviewed the 3-line diff adding a push trigger on main to ci-build.yml.

Verified:

• permissions: contents: read unchanged — no security impact from the new trigger (pushes to main require write access anyway).
• Concurrency group ci-build-${{ github.ref }} is per-ref, so main runs and PR runs won't cancel each other.
• No double-run on PR merge: pull_request defaults to opened/synchronize/reopened (no closed), so only the push event fires for the merge commit.
• All 11 checks pass.

Clean and correct. Approving.
