Bartok9 35655298e6 fix(gateway): prevent TTS voice messages from accumulating across turns ...

Fixes #160

The issue was that MEDIA tags were being extracted from ALL messages
in the conversation history, not just messages from the current turn.
This caused TTS voice messages generated in earlier turns to be
re-attached to every subsequent reply.

The fix:
- Track history_len before calling run_conversation
- Only scan messages AFTER history_len for MEDIA tags
- Add comprehensive tests to prevent regression

This ensures each voice message is sent exactly once, when it's
generated, not on every subsequent message in the session.
