fix(copilot): regenerate lockfile with npm 11.11.0 to match deploy

Deploy on DigitalOcean (npm 11.11.0) was failing `npm ci` with:

  Missing: @emnapi/[email protected] from lock file
  Missing: @emnapi/[email protected] from lock file

The previous lockfile was generated with npm 11.6.2, which does not
emit top-level `node_modules/@emnapi/*` entries for optional deps.
Regenerated with npm 11.11.0 so `optionalDependencies` from
package.json get the top-level lockfile entries that the deploy's
stricter `npm ci` requires.

`npm ci` now passes locally on 11.11.0.
