Extending

Two extension points cover nearly everything.

• Writing a processor : add your own logic to the chain, such as redacting text before it reaches the LLM, logging transcripts, hanging up on a keyword, or counting words. A struct embedding *processor.Base and one method.
• Writing a service : add an STT, LLM or TTS provider. Usually one interface method; the shared base handles frames, metrics, tracing, interruption and the tool loop.

Read Processors first, particularly the part about the two goroutines. It is the thing that catches people out.
