CYA-WP-0005 T05 done (ralph iter 5): Minimal Profile 1 (Reflexion verbal) spike

- Added KIND_REFLECTION + remember_reflection() helper in memory (thin, exported).
- Wired into run_retrospection(): optional 'capture verbal lesson' step at end.
- Main recall now includes reflections for preferential activation.
- Final LLM response + explain surface verbal reflections when activated.
- Added roundtrip test + import updates.
- Small README note.
- All changes small/inspectable, safety preserved (still through RiskClassifier).
- T05 acceptance criteria met with working end-to-end spike.

Committed as ralph iter 5. Ready for T06+ or close.
