Description

To ensure file format compatibility, let's fuzz test by making SQLite generate complex databases, and ensure that Turso is able to read them correctly.

Contributor guide

Research direction
Set up a fuzz testing harness in Rust (e.g., using cargo fuzz) that generates random SQLite databases and uses Turso to read them, then look for any mismatches or crashes.
