Create demo GIF for README

[rohitgs28]

Summary

A 20-30 second GIF showing QueryWise in action is the single biggest driver of GitHub stars. People decide to star within 5 seconds of landing on the README.

What the GIF should show

1. Launch querywise connected to a sample SQLite DB
2. Type a natural language question ("show me users who signed up this week")
3. See the AI generate SQL in the SQL panel
4. See results appear in the results table
5. Type :explain to see the AI explain the query
6. Press Ctrl+E to export CSV
7. Press Ctrl+S to toggle safe mode

Tools

• vhs by Charm (recommended, scriptable)
• asciinema + agg for GIF conversion
• ttygif

The demo needs a sample SQLite database with realistic data. A script to generate it would be helpful.
