Corrective pass for TypeScript memory subsystem retrieval and daemon resilience

A Phase 3 memory subsystem review found deviations from the authoritative memory spec: retrieval scoring omitted recency decay, normalized momentum, live-state retrieval bias, and multiplicative tier boost; short-term memories were still eligible for episodic retrieval; the memory daemon did not reconnect after LISTEN connection errors; ILIKE patterns used unescaped user text; extractor errors could disappear from fire-and-forget timeouts; and memory migrations lacked partitioning/seed data details.
