/**
 * SessionConsolidator — Hermes-inspired automatic memory extraction.
 *
 * Hermes Agent syncs conversation turns to memory after each response and
 * extracts memories on session end. This module replicates that loop for
 * cortex-engine:
 *
 *   - observe / wonder / speculate call notifyObservation() after every write.
 *   - When pending count hits AUTO_THRESHOLD per namespace, dreamPhaseA
 *     (NREM: cluster → refine → create) fires in the background without
 *     blocking the tool call that triggered it.
 *   - On process exit (SIGTERM / SIGINT), flush() runs dreamPhaseA across
 *     all namespaces with unprocessed observations.
 *
 * dreamPhaseA is intentionally lightweight — no REM (edges, abstraction,
 * FSRS scoring). Those still belong in the scheduled full `dream` cycle.
 * The point is that raw observations do not sit unprocessed across session
 * boundaries; they become searchable memories within the same session.
