fix: add --auto-memory support to agent mode

The --auto-memory flag was not being passed to run_agent_mode() and
send_auto_memory_reminder() was not being called after agent task
execution.

Changes:
- Pass auto_memory parameter to run_agent_mode()
- Add auto_memory parameter to run_agent_mode() function signature
- Call agent.set_auto_memory(true) when flag is enabled
- Call send_auto_memory_reminder() after execute_task() in agent mode
