Michael Simard 5964cadf94 Initial commit: Discord stock price bot with hourly PYPL updates
Implemented Discord bot for automated stock price tracking and reporting with the following features:

- Hourly PayPal (PYPL) stock price updates during NYSE market hours
- Custom branding for PYPL as "Steaks Stablecoin Value"
- Manual stock price queries via !stock and !price commands
- Multi-provider stock API support (Yahoo Finance and Finnhub)
- NYSE market hours detection with holiday awareness
- Discord embed formatting with color-coded price changes
- Docker containerization for consistent deployment
- Comprehensive documentation and deployment guides

Technical stack:
- Python 3.9+ with discord.py
- Finnhub API for stock price data
- APScheduler for hourly automated updates
- Docker support for local and Unraid deployment
