* Fix VoiceAgent to use run_manager instead of job_manager
VoiceAgent.__init__() was incorrectly using job_manager parameter
when ToolExecutionManager expects run_manager. This was causing
the error: "VoiceAgent.__init__() got an unexpected keyword
argument 'run_manager'".
Changes:
- Update VoiceAgent to accept and use run_manager instead of job_manager
- Update VoiceSleeptimeAgent to accept run_manager parameter
- Update imports to use RunManager instead of JobManager
- Pass run_manager to ToolExecutionManager in VoiceAgent._execute_tool
* docs: Add new examples to documentation
- Introduced "Your First Agent" example to guide users in creating a Letta agent and understanding its memory capabilities.
- Added "Attaching and Detaching Memory Blocks" example to demonstrate dynamic memory management for agents.
- Updated navigation in docs.yml to include links to the new examples.
These additions enhance the learning resources available for users working with Letta agents.
