feat(recall): thread-aware activation seed for nlg soul path [issue 7]

- Cache bell node result in engram_compile state (engram_compile_bell_node)
  so handle_chat affective_prefix reads the cached value instead of firing
  a duplicate engram query for distress signals (Issue 2)

- Cache primary activation result in engram_compile state
  (engram_compile_activation_json) using nodes0 from engram_compile_multi

- Replace redundant engram_activate_json(message, 2) in strengthen_chat_nodes
  with state_get(engram_compile_activation_json) - eliminates a third
  activation query per turn (Issue 7)

- engram_compile already has object-boundary truncation and cross-set
  dedup via engram_nodes_merge/engram_dedup_nodes (Issues 1, 6, 9)
