Replace single-stage MemoryConsolidator with a two-stage architecture: - Consolidator: lightweight token-budget triggered summarization, appends to HISTORY.md with cursor-based tracking - Dream: cron-scheduled two-phase processor that analyzes HISTORY.md and updates SOUL.md, USER.md, MEMORY.md via AgentRunner with edit_file tools for surgical, fault-tolerant updates New files: MemoryStore (pure file I/O), Dream class, DreamConfig, /dream and /dream-log commands. 89 tests covering all components.
