TS Reset - Improved TypeScript's Built-in Typings

Without ts-reset:

- 🚨 .json (in fetch) and JSON.parse both return any
- 🤦 .filter(Boolean) doesn't behave how you expect
- 😡 array.includes often breaks on readonly arrays

ts-reset smooths over these hard edges, just like a CSS reset does in the browser.

With ts-reset:

- 👍 .json (in fetch) and JSON.parse both return unknown
- ✅ .filter(Boolean) behaves EXACTLY how you expect
- 🥹 array.includes is widened to be more ergonomic
- 🚀 And several more changes!
