rnd(M03): extract streaming target planner

Work-Package: M03-RND-STREAMING-PLANNER-001
Agent: sindo-main-codex
Tests: planner/facade/focus/coordinate/manifest/shutdown contracts, seven-checkpoint dry-run, repository gates
Fidelity: preserves wanted/retained radii, boundary prefetch, editor preview, queue priority and cache/render behavior
