[build-deploy-embed-agy-agents-cli] Missing repository clone step in Set Up Your Environment

[primalkarma]

Description:

Section Affected: Step 2 (Set Up Your Environment) / Step 3 (Seed Firestore and Run the Starter App)

Issue: The codelab instructs users to run uv run python scripts/seed_firestore.py and uv run uvicorn src.main:app, but it does not provide the git clone command (or source repository URL) to download the starter code into Cloud Shell.

Suggested Fix: Add the starter repository git clone <REPO_URL> and cd commands in Step 2 under environment setup before the Firestore seeding step.
