AI Summary: This issue proposes adding a dataset of currency symbols (ISO 4217 codes to symbols) to the repository under a `data/currency-symbols/` directory. A manually triggered GitHub Actions workflow will then publish this data to a CDN under a `/v1/currencies/symbols.json` endpoint. The task also includes creating documentation for this new endpoint and updating the README.

The goal is to support configurable update intervals (e.g., minute-by-minute, hour-by-hour) while maintaining backward compatibility with existing date-based URLs and JSON output. This involves changes to the CLI, GitHub Actions, and the response format.
