//! # rustywallet-tx
//!
//! Bitcoin transaction building, signing, and serialization.
//!
//! ## Features
//!
//! - Build transactions with multiple inputs and outputs
//! - Automatic coin selection
//! - Fee calculation (vsize-based)
//! - Sign P2PKH and P2WPKH inputs
//! - Serialize transactions for broadcasting
//!
//! ## Quick Start
//!
//! ```rust
//! use rustywallet_tx::prelude::*;
//! use rustywallet_keys::prelude::PrivateKey;
//!
//! // Create a UTXO
//! let utxo = Utxo {
//!     txid: [0u8; 32],
//!     vout: 0,
//!     value: 100_000,
//!     script_pubkey: vec![0x00, 0x14, /* ... 20 bytes ... */],
//!     address: "bc1q...".to_string(),
//! };
//!
//! // Build transaction
//! let unsigned = TxBuilder::new()
//!     .add_input(utxo)
//!     .add_output(50_000, vec![/* scriptPubKey */])
//!     .set_fee_rate(10) // 10 sat/vB
//!     .build()
//!     .unwrap();
//!
//! println!("Fee: {} sats", unsigned.fee());
//! ```
//!
//! ## Signing
//!
//! ```rust,ignore
//! use rustywallet_tx::{sign_p2wpkh, Transaction};
//! use rustywallet_keys::prelude::PrivateKey;
//!
//! let private_key = PrivateKey::random();
//! let mut tx = unsigned.tx;
//!
//! // Sign P2WPKH input
//! sign_p2wpkh(&mut tx, 0, 100_000, &private_key).unwrap();
//!
//! // Serialize for broadcast
//! let hex = tx.to_hex();
//! ```
