restructure: hippocampus/ for memory, subconscious/ for agents

hippocampus/ — memory storage, retrieval, and consolidation:
  store, graph, query, similarity, spectral, neuro, counters,
  config, transcript, memory_search, lookups, cursor, migrate

subconscious/ — autonomous agents that process without being asked:
  reflect, surface, consolidate, digest, audit, etc.

All existing crate::X paths preserved via re-exports in lib.rs.
