soul: persist sessions across restarts via local snapshot

On startup, prefer the local engram snapshot if it has >50 nodes. HTTP Engram is only used on first boot (no snapshot yet). This means sessions, conversation history, and in-process state survive daemon restarts. awareness.el: sync source with compiled binary (periodic mem_save on heartbeat was already in the binary but not in source). Rebuilds soul.c with the new startup logic and ships updated binary.
