Tag distress exchanges as BellEvent nodes in auto_persist, include recent emotional context in engram_compile, preserve bell-turn history across session boundary.

feat(memory): emotional salience tagging and cross-session distress persistence

Neuron Soul CI / build (pull_request) Successful in 5m36s

- auto_persist: detect bell level (soft/hard) on every user message using
  safety_detect_bell_level; write a dedicated BellEvent engram node with
  calibrated salience alongside the Conversation node when a bell fires.
  Tag the Conversation node with bell:soft/bell:hard and 'affective' for
  direct discovery without scanning all chat nodes.

- auto_persist: track per-session bell count, dominant level, and last
  signal in state (session_bell_count/level/signal keys) so downstream
  functions can act on the emotional history without re-scanning engram.

- engram_compile: include the top-1 most recent BellEvent node within 72h
  in every context build. Distress context from earlier turns (same or
  recent session) automatically travels into all subsequent LLM calls.

- hist_trim_with_bell_guard: replace hist_trim at the handle_chat call site.
  Before evicting the oldest turn from the 20-turn window, inspect the user
  message for bell signals. If a bell was present, write a preservation
  BellEvent to engram before dropping the turn so the full message survives
  the rolling window.

- session_hist_save: after writing the history node, check session bell
  counters. On the first save where bell_count > 0, write a
  session:emotional-summary BellEvent node with distress signal, count,
  and dominant level. A state flag prevents duplicate writes on subsequent
  saves in the same session.

fix(chat): fix auto_persist timestamp extraction and bell label uniqueness

Neuron Soul CI / build (pull_request) Has been cancelled

Details

- engram_compile: BellEvent nodes do not carry created_at in the engram
  node JSON; extract the unix timestamp from the embedded ' | ts:NNNNN'
  pattern in the content string instead. Fall back to created_at/updated_at
  if the marker is absent. Guard str_to_int against empty string so the 72h
  recency check never silently treats every node as epoch-0 stale.

- auto_persist: append the current unix timestamp to the BellEvent label
  ('bell:soft:1749876543') to make it unique per turn. The previous label
  ('bell:soft') was the same for every soft bell, causing engram to treat
  all subsequent writes as updates to the same node.
