[WIP] Add missing dependency lock file to resolve CI failure for MCP server

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original description:

The related PR for issue #1 ([WIP] Implement Azure Functions-based MCP Server) is failing CI due to a missing dependencies lock file (error: 'Dependencies lock file is not found in /home/runner/work/HelloMCP/HelloMCP. Supported file patterns: package-lock.json,npm-shrinkwrap.json,yarn.lock').

Solution Context:

• The build process expects a dependency lock file to ensure consistent installs during CI.
• This is typical for Node.js projects, and the lock file can be generated by running npm install (for package-lock.json) or yarn install (for yarn.lock).

Action Required:

• Generate a dependency lock file in your project root (e.g., by running npm install or yarn install).
• Commit the generated package-lock.json or yarn.lock to the repository.
• If using npm, run:

  npm install
  git add package-lock.json
  git commit -m "Add package-lock.json to fix CI dependency lock error"
  git push

• If using yarn, run:

  yarn install
  git add yarn.lock
  git commit -m "Add yarn.lock to fix CI dependency lock error"
  git push

• Re-run the workflow to confirm the fix.

Reference (CI failure log):

Dependencies lock file is not found in /home/runner/work/HelloMCP/HelloMCP. Supported file patterns: package-lock.json,npm-shrinkwrap.json,yarn.lock

Please ensure this context is included in issue #1 so the Copilot coding agent can address it.
