[NO QA] Use postCodeReviewResults.sh from claude-review-toolkit

[kacper-mikolajczak]

Explanation of Change

Adopts the new postCodeReviewResults.sh helper added in Expensify/GitHub-Actions#66. Replaces the inline jq + while-loop in the Post code review results step with a single script call. Bumps the claude-review-toolkit pin to the SHA that introduces the script.

No steady-state behaviour change: 0 violations -> +1 reaction; N violations -> N inline comments via createInlineComment.sh (failures per comment swallowed with || true); empty STRUCTURED_OUTPUT -> ::error:: + exit 1.

This is part of slice 2 of the centralisation effort. The toolkit pin currently points at the SHA on the toolkit PR branch and will be re-stamped to the merged-main SHA once Expensify/GitHub-Actions#66 lands.

Fixed Issues

PROPOSAL:

Tests

N/A - CI infrastructure with no user-facing behaviour change. Validation happens via the workflow itself running on this PR (will only fully validate once the toolkit SHA is re-stamped post-merge of Expensify/GitHub-Actions#66).

1. Verify that no errors appear in the JS console

Offline tests

N/A - CI infrastructure change; doesn't affect runtime offline behaviour.

QA Steps

@Julesssss and @kacper-mikolajczak will check out some AI Reviewer workflow runs on real PRs after merge.

• Verify that no errors appear in the JS console
