PR Summary

Medium Risk
Adds new on-chain parsing/join logic and expands the global dex_solana_base_trades union, so incorrect indexing or join assumptions could create missing/duplicated/mis-attributed trades.

Overview
Adds a new Solana DEX integration for Byreal by introducing incremental models to extract swap instructions (byreal_solana_stg_raw_swaps) and derive raw trades by joining to SPL token transfers (byreal_solana_base_trades, including trade_source, vaults, mints, and amounts).

Exposes Byreal trades via a dedicated byreal_solana_trades view over dex_solana_trades, adds schema metadata/tests for the new models, and includes Byreal in the dex_solana_base_trades union so it flows into the global Solana DEX dataset.
