v0.6.1

Changed

• memory_search_global: memory_dirs parameter is now optional (defaults to None). At least one of memory_dirs or memory_dir must be provided. Empty strings in memory_dirs are filtered out
• memory_evidence: max_lines default increased from 8 to 12, reducing information loss for sections with longer content
• memory_state_from_note: docstring now documents auto-improve behavior (no_auto_improve, auto_improve_add) and response fields (updated_sections, section_counts, stale_count, warnings)
• memory_auto_restore: docstring now documents response structure fields (project_state, agent_state, active_tasks, etc.)
