release: update DEX protocol support for v4.0.9

Sync supported DEX IDLs from bitquery/solana-idl-lib, upgrade protocol builders, and keep trade submission hot paths free of RPC query calls.

Include exact-output coverage, token-account setup fixes for WSOL and stable pairs, and low-latency transaction build improvements.
