//! Parse Pump.fun quote-mint edge cases through solana-streamer's parser SDK re-export.
//!
//! Defaults cover:
//! - 19-account `create_v2` with explicit WSOL quote mint.
//! - 16-account `create_v2` with no quote mint account.
//!
//! Usage:
//! ```bash
//! cargo run --example parse_pumpfun_quote_cases --release
