Summary

Messages sent to Telegram appear as duplicates - each message appears twice. When using TTS + text together, both audio AND text get duplicated. Related to multi-step tool sequences - intermediate narration gets sent as separate messages.

Steps to reproduce

1. Connect agent to Telegram channel
2. Send a message requiring multiple tool calls (e.g., TTS + message)
3. Each text block gets sent separately, resulting in duplicates

Expected behavior

Only one message should be sent to Telegram per user interaction.

Actual behavior

Each text block gets sent separately, resulting in duplicate messages. TTS audio gets sent twice, text gets sent twice. Workaround: restart gateway to clear stuck state.
