fix(release): remove duplicate history tool script

Remove the duplicate package.json history:tool:check script key before finalizing v3.16.4-5 release assets.

The duplicate key caused esbuild/Vite to warn during the local release build even though the command value was identical. Keeping a single script preserves behavior and makes the formal release build log clean.

Validation: pnpm exec prettier --check package.json; pnpm history:tool:check; pnpm typecheck; git diff --check.
