In @.github/workflows/node.js.yml:
- Line 19: Update the Node.js version matrix in the workflow to match the
package.json engines.node contract, replacing the unsupported 18.x, 20.x, and
22.x entries with 24.x and 26.x. If older versions must remain supported,
instead update the engines.node declaration to reflect that contract.
