fix: reset retry counters after compression and stop poisoning conversation history

Browse source 
Three bugfixes in the agent loop:

1. Reset retry counters after context compression. Without this,
   pre-compression retry counts carry over, causing the model to
   hit empty-response recovery immediately after a compression-
   induced context loss, wasting API calls on a now-valid context.

2. Unmute output in the final-response (no-tool-call) branch.
   _mute_post_response could be left True from a prior housekeeping
   turn, silently suppressing empty-response warnings and recovery
   status that the user should see.

3. Stop injecting 'Calling the X tools...' into assistant message
   content when falling back to prior-turn content. This mutated
   conversation history with synthetic text that the model never
   produced, poisoning subsequent turns.
