Revive heartbeat state and cool empty-room loops

 - if a new musing substantially overlaps one of the last few musings, either sharpen the genuinely new delta or discard it
+- repeated "no new messages / no smoke / no post" observations are low-signal bookkeeping, not a deep new memory; merge or trim them aggressively instead of letting them annex the state
 - treat `semanticVector` metadata, `memory_resonance`, and `incubation` as real organs rather than decorative bookkeeping
 - a thought is allowed to stay private for several runs while it deepens, but only if it is actually gaining connective tissue instead of being gently embalmed
