What does this PR do?

This PR updates the webui/package-lock.json file to sync it with the current webui/package.json.

Why is this necessary?

Currently, building the Docker image from a fresh clone fails at the webui-builder stage (Step 5/23 : RUN npm ci).

Because npm ci requires absolute synchronization between package.json and the lockfile, the build crashes complaining about a missing dependency (diff@9.0.0) in the lockfile. It appears package.json was updated previously, but the newly generated lockfile was accidentally omitted. This PR restores that synchronization so the Docker build completes successfully.

**Error encountered during docker build -t nanobot .**:

Step 5/23 : RUN npm ci
npm error `npm ci` can only install packages when your package.json and package-lock.json or npm-shrinkwrap.json are in sync. Please update your lock file with `npm install` before continuing.
npm error
npm error Missing: diff@9.0.0 from lock file

Changes Made

• Navigated to the webui/ directory and ran npm install to freshly resolve the dependency tree.
• Committed the updated package-lock.json so that npm ci can execute successfully in the Dockerfile.

Testing

• Verified docker build -t nanobot . completes successfully from scratch.
• Verified no unintended package upgrades occurred outside of resolving the missing dependencies.

[Re-bin]

LGTM. This is the minimal lockfile repair for the already-declared diff dependency; it does not upgrade or alter unrelated packages.

A clean npm ci succeeds and the WebUI production build completes locally. GitHub Actions is also green across the full matrix.
