docs(honcho): wizard cadence default 2, prewarm/depth + observation + multi-peer

- cli: setup wizard pre-fills dialecticCadence=2 (code default stays 1
  so unset → every turn)
- honcho.md: fix stale dialecticCadence default in tables, add
  Session-Start Prewarm subsection (depth runs at init), add
  Query-Adaptive Reasoning Level subsection, expand Observation
  section with directional vs unified semantics and per-peer patterns
- memory-providers.md: fix stale default, rename Multi-agent/Profiles
  to Multi-peer setup, add concrete walkthrough for new profiles and
  sync, document observation toggles + presets, link to honcho.md
- SKILL.md: fix stale defaults, add Depth at session start callout
