Goal Move beyond the small ASSIST.MEM slots by adding an inspectable on-disk conversation and memory database that remains useful on DOS-class systems. Acceptance criteria - Conversation records use a bounded, DOS-friendly file format with clear size limits. - The assistant can recall recent useful facts across sessions without scanning unbounded transcripts. - Users can inspect, reset, or compact the local memory from the shell. - Memory recall is reported in ASSIST_REPLY evidence records.
