- Extend on-chain Pool layout (is_cashback_coin, 7-byte reserved, 244 bytes)
with backward-compatible decode for 236-byte legacy accounts
- Decode Buy/Sell program logs manually: min_base_amount_out, ix_name,
cashback fields; optional sell cashback when payload >= 368 bytes
- Set ix_name on buy / buy_exact_quote_in instructions; merge new fields
in CPI log merger
- Add read_i64_le helper and pool layout unit test

spl-token-group-interface 0.7.2 changed TokenGroup.update_authority to
MaybeNull<Pubkey>, while spl-token-2022 10.0.0 still expects
OptionalNonZeroPubkey, causing E0308 build failures. Pinning to 0.7.1
aligns transitive deps until upstream publishes a compatible release.
