KIP-1050 — Consistent error handling for Transactions

Accepted Kafka 4.1 TransactionsClient

Defines a comprehensive error taxonomy for Kafka transactional and idempotent producer APIs — classifying each error as retriable, abortable, or fatal — and aligns error handling behavior across all client SDK implementations (Java, librdkafka, Go, .NET, Python). Inconsistent error handling across SDKs and incomplete error specifications in KAFKA-7787/KAFKA-14439 made it difficult for non-Java clients to implement correct transactional semantics.
