ni5arga/stock-tui ? reverse-engineered prompt

Build me a terminal app that tracks real time prices for stocks and crypto in one place.

I want a clean watchlist view where I can add symbols like AAPL, TSLA, BTC USD, and ETH USD, see current price, change, and trend, then open a simple chart for the selected asset. It should update automatically, let me refresh manually, search and filter the list, sort by name, price, or change percent, and move around with keyboard shortcuts like a vim style terminal app.

Please include support for a few data sources, at least a crypto source, a stocks source, and a combined mode, with a default config file the app can read from the current folder or a user config location. Make the UI look polished in the terminal, with a footer, help screen, and different chart ranges like 1 hour, 24 hours, 7 days, and 30 days. If you need to check current docs for any library behavior, go ahead and look them up online.
