feat(honcho): wizard cadence default 2, surface reasoning level, backwards-compat fallback

Setup wizard now always writes dialecticCadence=2 on new configs and
surfaces the reasoning level as an explicit step with all five options
(minimal / low / medium / high / max), always writing
dialecticReasoningLevel.

Code keeps a backwards-compat fallback of 1 when dialecticCadence is
unset so existing honcho.json configs that predate the setting keep
firing every turn on upgrade. New setups via the wizard get 2
explicitly; docs show 2 as the default.

Also scrubs editorial lines from code and docs ("max is reserved for
explicit tool-path selection", "Unset → every turn; wizard pre-fills 2",
and similar process-exposing phrasing) and adds an inline link to
app.honcho.dev where the server-side observation sync is mentioned in
honcho.md. Recommended cadence range updated to 1-5 across docs and
wizard copy.
