KIP-803 — Add Task ID and Connector Name to Connect Task Context

Discussion ConnectMetrics

Exposes the task ID and connector name to `SourceTask` and `SinkTask` implementations via the `TaskContext` interface so connectors can use them for custom metrics, logging, or debugging. While KIP-449 added these values to the SLF4J MDC for log enrichment, there was no programmatic API for connectors to access them directly.
