self-review 2026-05-28: checkpoint ISE decay fix + auto-linking for MCP nodes

Browse Source 
Three changes:

1. Fix checkpoint ISE temporal_decay_rate: engram_emit_ise_internal was
   hardcoded to 0.0 (global 168h default) instead of 2.310 (Working-tier
   48h). Result: checkpoint ISEs accumulated at 3.5x intended rate.

2. Raise CHECKPOINT_INTERVAL 1→10: checkpoint ISE fires on every single
   node write, producing 2:1 checkpoint:content ratio in ISE stream.
   MCP routes still call engram_write_binary_el explicitly after each
   important write, so no knowledge durability is lost.

3. Add auto_link_content_node to server.el: route_neuron_memory and
   route_neuron_knowledge_capture were creating nodes with zero edges —
   invisible to BFS traversal, only reachable via lexical/semantic seed.
   New helper runs BM25 over top-20 results, skips ISE nodes (which
   dominate the 14K-node corpus), connects up to 3 related nodes.
