* fix(core): disable account_data_size limit and add meta.err checking The 12.5MB setLoadedAccountsDataSizeLimit was causing all buy transactions to fail with MaxLoadedAccountsDataSizeExceeded since pump.fun migrated to Token-2022. Transactions landed on-chain (fees paid) but inner instructions were rejected — the bot paid gas for nothing. Changes: - Disable account_data_size in all bot configs (Token-2022 needs >12.5MB) - Add meta.err check in get_buy_transaction_details() for clear error reporting when transactions fail on-chain - Include tx signature in platform_aware.py error messages for debugging Tested: full buy→sell→cleanup cycle works on pump_fun with geyser listener. * fix(core): check meta.err in confirm_transaction to detect failed txs Solana transactions can be "confirmed" (included in a block) but still fail execution if inner program instructions are rejected. Previously, confirm_transaction only checked that the tx landed on-chain, causing silent failures in buy, sell, and cleanup operations. Now fetches the transaction result after confirmation and checks meta.err, returning False when the transaction failed. This fixes the ATA cleanup issue where sells were silently failing with Custom: 6003 errors, leaving non-zero token balances. * fix(core): treat failed tx fetch as unconfirmed in confirm_transaction When _get_transaction_result returns None (RPC failure, timeout, etc.), the function was falling through to return True — silently treating an unknown state as success. Now returns False with a warning log. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
