A small, testable CLI and data-pipeline project demonstrating:

• Package architecture and editable installation (pip install -e .)
• Web scraping with requests + BeautifulSoup
• Persistence to SQLite database with idempotent inserts
• A simple CLI for adding/listing/looking up contacts
• Unit tests for validators and core logic
• A scheduler example (APScheduler) to automate periodic jobs
