mind-stream: her stream of thought, offline (cut stream-thoughts steps 2-5)

The stream organ projects her own state through Ghostlight's Projector
(a pinned git dependency), lets a base model continue it raw over loopback
Ollama, keeps the continuation least near her earlier thoughts by the
daemon's scores, and admits it as one thought with its whole trace.
mind-stream --instance <slug> [--once] [--dry-run]. Cadence is derived from
her newest thought; nothing is delivered to any Persona.
