feat: PumpSwap/PumpFun improvements, align with pump-public-docs, sync IDL

Browse Source 
- Re-apply PumpSwap pool lookup, lib/utils/seed changes (no Fastlane)
- pump-public-docs: Mayhem fee recipient at index 11 use WSOL ATA; random mayhem fee recipients (PumpSwap + PumpFun); Pool decode 244 bytes
- Sync idl (pump.json, pump_amm.json, pump_fees.json) from pump-fun/pump-public-docs
