🔍 chore(.gitignore): add qdrant_storage to ignore list

🆕 feat(.vscode/launch.json): add launch configuration for FastAPI app
The qdrant_storage directory is now added to the ignore list to prevent it from being tracked by git. A new launch configuration for FastAPI app is added to the .vscode/launch.json file. This configuration allows for debugging the app with uvicorn and sets the port to 7860, reloads the app on changes, and sets the log level to debug.
