feat(council): add D/P (Deterministic/Probabilistic) dual-group mode

- New 'mode' parameter: personality (default) or dp
- D group: grounded, feasibility-first (Freethinker + Arbiter)
- P group: exploratory, reframing-first (Freethinker + Arbiter)
- Meta-Arbiter merges best ideas from both groups
- Full prompt templates for ideation, assessment, bridge, and merge
- Orchestration docs for single-round and multi-round D/P flows
- Inspired by Flynn's dual-council architecture, adapted for OpenClaw subagents
