Update README.md to reflect new project focus on lagged oil and unemployment charting. Revise installation instructions, quickstart guide, and repository structure. Modify scripts for data fetching and plotting, and add a new SQLite database for storing FRED data. Introduce a startup script to streamline setup and execution.
- Introduced `scripts/refresh_data.py` to download UNRATE and WTI data from FRED and store it in a SQLite database.
- Added `startup.sh` script to set up a Python virtual environment and install dependencies for offline use.
- Updated `repo-context.txt` to reflect the new scripts and their purposes.
Removed the `lagged_oil_unrate_chart_styled.py` script as it is no longer needed. Added a `.gitignore` file, a `requirements.txt` for dependencies, and a `scripts/` directory for future development.
