Fix Node 20 CI install failure by aligning Rollup peer dependency

[Copilot]

Node 20 CI was failing at npm ci with an ERESOLVE conflict after the version-bump consolidation. The failure came from a peer range mismatch between rollup@4.x and @rollup/plugin-json@6.0.0.

• Root cause

  • @rollup/plugin-json@6.0.0 declared rollup peer support up to ^3, while the repo now pins rollup@4.52.5.
  • This made dependency resolution fail in CI before build/test steps.

• Dependency alignment

  • Bumped @rollup/plugin-json from ^6.0.0 to ^6.1.0 in package.json.
  • Updated package-lock.json to reflect the resolved graph.

• Resulting behavior

  • Keeps the Rollup 4 bump intact.
  • Removes the install-time peer conflict for Node 20 CI.

{
  "devDependencies": {
    "@rollup/plugin-json": "^6.1.0",
    "rollup": "4.52.5"
  }
}
