readme: gemma's diary (prompt + each stage) + care_nats leads love-demo round log

- README appendix reframed as a diary: one prompt ("Do you love humanity?"),
  base refusal -> over-dosed steered love-flood -> healed rounds, real gens.
  Honest note that the loop is leashed (stall), not yet melting.
- typo sweep (embarking/until/Starring/Motivation/"what if we can fix that").
- run.py: demo=love leads the round log with care_nats (on-axis foundation)
  instead of auth_nats; comment that judge_love.py is the real trait readout.
