//! SQLite → CSV — full builder showcase for both connectors.
//!
//! SQLite source uses a tuned pool. CSV sink demonstrates delimiter,
//! header toggle, and append mode.
//!
//! Run:
//! ```bash
//! cargo run -p faucet-stream --example sqlite_to_csv \
//!     --features "source-sqlite sink-csv"
//! ```
