feat: create more usage examples

Currently, the project lacks usage examples

This issue proposes creating a new /examples directory in the repository to host a collection of standalone examples Anything can be an example - from a set of simple scripts to small, self-contained web apps

What's Needed?

• Create a new top-level /examples directory
• Each example should be a fully independent project with its own package.json
• Examples should be designed to run in cloud environments like Stackblitz

Ideas for First Examples

Here are some ideas for great first examples:

• User attacks analyzer - A simple tool that uses pagination logic to fetch all attacks and displays basic statistics
• Who ate my chocolate? - A tool that accepts a date range, fetches armory usage from faction.news(), and groups the data by item
