Problem

When TTS is enabled, the typing indicator (chat action) stops as soon as the model run completes, but the TTS audio generation and sending happens after in the dispatch phase.

On Telegram (and likely other platforms), this causes the audio playback to be cut off when the bot goes back to idle state.

Expected Behavior

The typing/recording indicator should remain active until the TTS audio is fully generated and sent to the user.

Steps to Reproduce

1. Have TTS enabled
2. Send a message that triggers a longer response
3. The typing indicator stops while the audio is still being generated
4. Audio gets cut off

Suggested Fix

Keep the typing controller active through the TTS generation phase in dispatch, only calling markDispatchIdle() after the audio message is actually sent.
