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.
