Summary

Fixes #327

Use null-prototype value maps so {{__proto__}} is filled in the builder preview and included in iteration labels, matching the emitted CLI command. Covers scalar and array values in zip and cross modes with five mock-DOM regression cases. Includes rebuilt dist/ files and a changelog fragment.

The change is limited to preview value collection; no CLI syntax or resolver behavior changes.

Validation

• All five new regression cases failed before the fix and passed afterward.
• npm run lint
• npm run build
• npm test (including enforced coverage thresholds)

Checklist

• npm run lint, npm run build and npm test pass locally
• If src/ changed: the rebuilt dist/ is committed
• If the change is user-visible: a changelog fragment is included
• Behavior changes include tests or verification notes
• Commits are signed off (git commit -s)

Overlap note: #328 (hive, opened earlier) fixes the same issue #327 with the same Object.create(null) approach and is green, waiting on tide. If #328 merges first this PR will need a rebase; its extra zip/cross-mode and iteration-label coverage is worth keeping as a follow-up on top of #328 if so.
