Restructure into a three-tab app with Progress, goals, and Meditation

The UX redesign's first landing (spec in UX-REDESIGN.md): ContentView
becomes a Today / Progress / Settings TabView, "Routine" replaces
"Split" in every user-facing string and view name (code-level types
keep their names), and workout starting moves to shared
WorkoutStarter / StartedWorkoutNavigator plumbing.

- New Progress tab: weekly goal streaks, workout trends, per-exercise
  weight progression, achievements, and the full history list
  (WorkoutLogsView -> WorkoutHistoryView).
- Goals: stable categories workouts roll up to, managed from Settings.
- New Meditation exercise + starter routine; timed sits record to
  Apple Health as Mind & Body sessions.

// INDEPENDENT version counters (`RoutineDocument.currentSchemaVersion` and

// both correctly a Split written at a version the workout counter has already
// both correctly a Routine written at a version the workout counter has already
// reached would be misjudged. The forward-gate ceiling therefore has to be
// resolved per file (its location under `Documents/` tells us its type), so the
// scanner takes a `CeilingResolver` closure. A single-Int convenience init is
