fix: WSOL ATA creation in background with retry/timeout; silence unused and deprecated warnings

- lib: WSOL ATA creation moved to background to avoid blocking startup; ensure_wsol_ata adds 3 retries and 10s timeout
- lib: cfg(feature = "perf-trace") for DEFAULT_SLIPPAGE usage
- gas_fee_strategy, bloxroute, transaction_builder, async_executor, executor: prefix unused vars/params with underscore or allow
- pumpswap: add allow(deprecated) for get_program_accounts_with_config
