-- Text Aggregation Improvements:
-
-  - **Breaking Change**: `BaseTextAggregator.aggregate()` now returns
-    `AsyncIterator[Aggregation]` instead of `Optional[Aggregation]`. This
-    enables the aggregator to return multiple results based on the provided
-    text.
-  - Refactored text aggregators to use inheritance: `SkipTagsAggregator` and
-    `PatternPairAggregator` now inherit from `SimpleTextAggregator`, reusing
-    the base class's sentence detection logic.

-- Improved interruption handling to prevent bots from repeating themselves. LLM services that return multiple sentences in a single response (e.g., `GoogleLLMService`) are now split into individual sentences before being sent to TTS. This ensures interruptions occur at sentence boundaries, preventing the bot from repeating content after being interrupted during long responses.
