Good first issue: Add basic project README with usage example

[Dawaman43]

👋 Welcome! This is a beginner-friendly issue for anyone who wants to make their first contribution to xsql.

Problem

The project currently lacks a clear README that explains:

• What xsql is
• What problem it solves
• How to run or use it
• A small usage example

This makes it harder for new users (and contributors) to get started.

What needs to be done

• Create or improve README.md
• Include:
  • Short project description (2–3 sentences)
  • Installation steps
  • Basic usage example
  • Project goals / roadmap (optional)

Requirements

• Clear and simple language
• No deep Rust knowledge required
• Code examples should compile (if applicable)

Helpful pointers

• Look at READMEs from similar projects
• Keep it minimal and beginner-friendly
