self-review 2026-05-16: tier-based decay rates, implement knowledge_promote, ISE label extraction

Browse Source 
Three research-grounded improvements:

1. Tier-based temporal decay in el_runtime.c (engram_node_full, engram_node_layered):
   Working=48h, Episodic=72h, Semantic=336h, Procedural=720h half-lives.
   Grounded in ACT-R literature — differentiated decay by chunk type. The
   temporal_decay_rate field existed but was always 0 (global 168h for everything).
   New nodes now carry the correct half-life for their tier from creation.

2. Implement route_neuron_knowledge_promote in server.el (was a silent stub):
   Reads existing node, creates promoted-tier copy with supersedes edge,
   checkpoints. promote_knowledge MCP tool now has real effect.

3. ISE label extraction + offset support in route_neuron_state_events:
   POST now extracts 'event' field from content JSON as label (heartbeat,
   wm_promotion, etc.) instead of always writing 'state-event'. GET now
   accepts ?offset= for pagination to reach recent ISEs.
