Upgrade the build toolchain to Rollup 4 and modern plugins, replacing the deprecated terser plugin and updating the config for ESM. Requires Node 18+ and trims legacy dependencies.

Description

A clear and concise description of the PR.

Use this section for review hints, explanations or discussion points.

• Summary of changes
  • Bump rollup to ^4.59.0 and update @rollup/plugin-commonjs, @rollup/plugin-json, @rollup/plugin-node-resolve.
  • Replace rollup-plugin-terser with @rollup/plugin-terser; update import and add maxWorkers: 1.
  • ESM config fix: use createRequire(import.meta.url) to read package.json.
  • Remove preferConst from ESM/CJS outputs (option removed in newer Rollup).
  • Lockfile updates: add Rollup platform binaries, drop deprecated subdeps; update smoke test lockfiles.
• Reasoning
  • Keep the bundling stack current and supported (Rollup 4 is ESM-first; old terser plugin is deprecated).
  • Ensure compatibility and stable builds with modern plugin APIs.
• Additional context
  • Rollup 4 requires Node 18+. CI and local dev must run Node ≥18.
  • No public API or output format changes expected; this is a build tooling upgrade.

Docs

• Update build prerequisites to Node 18+.
• Note the switch to @rollup/plugin-terser in contributor/build docs.

Testing

• No new tests added. Smoke test lockfiles updated only.
• Validation to run:
  • npm run build succeeds on Node 18+.
  • ESM and CJS smoke tests pass (tests/smoke/esm, tests/smoke/cjs).
  • Verify generated files in dist/ (ESM/CJS and minified bundles) and check bundle size is within expected range.
