demo:orchestrator fails: missing required --subagent_urls argument

[Wirasm]

Description

Running npm run demo:orchestrator from samples/client/lit fails immediately because the npm script doesn't pass the required --subagent_urls CLI option to the orchestrator agent.

Steps to Reproduce

cd samples/client/lit
export GEMINI_API_KEY="..."
npm install
npm run demo:orchestrator

[ORCH] Error: Missing option '--subagent_urls'.
[ORCH] npm run serve:agent:orchestrator exited with code 2

Root Cause

The orchestrator's __main__.py requires --subagent_urls as a required CLI option:

@click.option("--subagent_urls", multiple=True, type=str, required=True)

But the npm script in package.json runs it without any arguments:

"serve:agent:orchestrator": "cd ../../agent/adk/orchestrator && uv run ."

Expected Behavior

npm run demo:orchestrator should start the required sub-agents (restaurant_finder, contact_lookup, rizzcharts) and pass their URLs to the orchestrator. For example, the script could:

1. Start sub-agents on known ports first
2. Pass their URLs via --subagent_urls http://localhost:10003 --subagent_urls http://localhost:10004 ...
