Raw Blame History

⚠️ Removed deprecated service-specific context and aggregator machinery, which was superseded by the universal LLMContext system.

Service-specific classes removed: AnthropicLLMContext, AnthropicContextAggregatorPair, AWSBedrockLLMContext, AWSBedrockContextAggregatorPair, OpenAIContextAggregatorPair, and their user/assistant aggregators. Also removed create_context_aggregator() from LLMService, OpenAILLMService, AnthropicLLMService, and AWSBedrockLLMService.

Base aggregator classes removed (from pipecat.processors.aggregators.llm_response): BaseLLMResponseAggregator, LLMContextResponseAggregator, LLMUserContextAggregator, LLMAssistantContextAggregator, LLMUserResponseAggregator, LLMAssistantResponseAggregator.

From the developer's point of view, migrating will usually be a matter of going from this:
```
context = OpenAILLMContext(messages, tools)
context_aggregator = llm.create_context_aggregator(context)
```
To this:
```
from pipecat.processors.aggregators.llm_context import LLMContext
from pipecat.processors.aggregators.llm_response_universal import LLMContextAggregatorPair

context = LLMContext(messages, tools)
context_aggregator = LLMContextAggregatorPair(context)
```
