WholeHistoryMultipleSystemMessages

WholeHistoryMultipleSystemMessages is a concrete implementation of the HistoryCompressionStrategy that handles scenarios where the conversation history contains multiple system messages.

This strategy:

1. Splits the history into blocks based on system message boundaries

2. Processes each block separately to generate TL;DR summaries

3. Maintains the chronological order of system messages while compressing the conversation

4. Preserves memory messages only in the first block to maintain context
