Seata distributed transaction skill. Covers a decision tree for selecting among the AT/TCC/SAGA/XA modes, the mandatory undo_log table for AT mode, useTCCFence in TCC mode for handling idempotency, suspension, and empty rollback, SAGA state machines for long-running workflows, global transaction timeout configuration (@GlobalTransactional timeoutMills), and read isolation enhancement (@GlobalLock + FOR UPDATE). Corrects common LLM mistakes: not knowing which of AT/TCC/SAGA to choose, not creating the undo_log table, making TCC Confirm non-idempotent, and ignoring watchdog handling.
