test(layout): compact layout.json back under the line ratchet

[lidge-jun]

Summary

dev is red on file-size ratchet: repository: #6721 and #6724 each added one explicit registration to scripts/test-layout/layout.json, and together they took it to 2000 lines, one over the 1999-line NEW_OVERSIZED ratchet. Each branch passed at its own head; the union does not, so every open PR's merge-ref CI now fails that test (seen on #6731, test 2/4).

Fold forty single-entry lines (file lines 1300–1339) into four-per-line rows, the compact form the file already uses. The parsed mapping is byte-for-byte unchanged (asserted with json.loads equality); the file drops to 1970 lines, leaving headroom for the other open PRs that register tests. The folded range avoids the hunks of the open layout-touching PRs; git merge-tree against #6725, #6727, #6728, #6731 and #6732 is clean.

Verification

• bun test tests/ci-workflows/file-size-ratchet.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts --timeout 120000: 27 pass, 0 fail.
• Parsed JSON equality before/after; wc -l: 2000 → 1970.
• tests/fixtures/test-layout-expected.json needs no change (inventory unchanged).

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

• Chores
  • Reformatted the test layout manifest; test-to-suite mappings remain unchanged.
