The main agent should coach the user, but nothing stored what the user wants to achieve or keep doing, and no routine ever checked in. This adds the data model and the interfaces the onboarding intake and the coach tools build on. - Schema: UserGoal, Habit, CheckIn (one per habit, goal or day and date) and DailyBrief, all keyed to the user's local calendar date, plus a coachKey on Routine that marks the main bot's coach check-ins. - Contracts (coach.ts): CoachRhythm, Goal, Habit, CheckIn, DailyBrief and CoachToday DTOs and the RPC inputs. - Repository (@rakazo/db coach.ts): goal, habit and check-in CRUD with per-user limits, upsertDailyBrief and loadCoachToday with streaks in the user's time zone. - coach-rhythm.ts: setCoachRhythm/getCoachRhythm keep up to three main bot routines (morning brief, evening check-in, weekly review) in the main conversation in step with the user's chosen times.
