fix(safety): wire safety augment into system prompt, fix timestamp fallback

- Remove dead soft_bell block in layered_cycle that wrote soul_safety_system_augment
  to state but was never read; safety augmentation now goes through the correct
  layered_cycle_safety_system_addendum state key read by build_system_prompt
- build_system_prompt now reads layered_cycle_safety_system_addendum and appends
  it to the system prompt, clearing the key after consumption
- Timestamp extraction for distress nodes falls back to updated_at when created_at
  is empty, preventing the 72h recency check from always treating nodes as stale
