- PumpFunParams::from_trade/from_dev_trade: add mayhem_mode Option; infer Mayhem
via is_mayhem_fee_recipient when None (fixes fee recipient / NotAuthorized 6000
when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.
- Update examples and latency script for new PumpFunParams signature.
- SWQoS and transaction builder adjustments for dependency changes.
