Fix memory leak in RedisKeysSourceTask

Problem

The sourceOffsets list in RedisKeysSourceTask was continuously growing without ever being cleared, causing a memory leak in long-running connectors.

Root Cause

• commitRecord() method added offsets to the list via addSourceOffset()
• commit() method was a no-op and never cleared the list
• The collected offsets were never actually used for any functionality

Solution

• Removed the unused sourceOffsets field and addSourceOffset() method
• Simplified commitRecord() to be a no-op with explanatory comment
• No functional impact since Redis key monitoring doesn't require offset acknowledgment

Why This Is Safe

Unlike RedisStreamSourceTask, the keys source connector uses Redis keyspace notifications which are fire-and-forget events that don't require acknowledgment. The RedisItemReader in LIVE mode handles state internally, making offset tracking unnecessary.

Fixes memory leak in production deployments monitoring high-volume Redis key changes.
