launcher.py failing due to missing agent_framework module

The latest version of the maf_fabric_sql branch has a bug when trying to run the launcher.py.

(venv) PS C:\Users\israeloros\Documents\Learning\Azure\Insiders\vteam\sql-agentic-app-with-fabric\backend> python launcher.py
[0] Initializing database connection...
[ConnectionManager] Using cached credentials
✅ Database authentication successful
[1] Initializing services...
Error in combined launcher: No module named 'agent_framework'
Services stopped.

Upon further investigation, the issue is that the provided requirements.txt file does not contain the **agent-framework** module. The error seems to be generated while importing the banking_app.py module in the launcher.py, because the banking_app.py has the following two lines:

from agent_framework import ChatAgent
from agent_framework.azure import AzureOpenAIChatClient

Start with requirements.txt and the imports in banking_app.py, then run launcher.py in a fresh virtual environment to reproduce the missing-module error. Done means the declared dependencies install successfully and launcher.py proceeds past service initialization without the agent_framework import failure.
