/**
 * A service for handling volume planning operations across microcycles.
 *
 * RESPONSIBILITIES:
 * - Calculate set counts for exercises across a microcycle
 * - Apply progressive overload rules (baseline + historical adjustments)
 * - Handle recovery exercise identification
 * - Enforce volume limits (per exercise, per muscle group per session)
 *
 * RELATED SERVICES:
 * - {@link WorkoutMicrocycleService} - Calls this to get set plans before generating sessions
 * - {@link WorkoutSessionService} - Uses the output to generate actual sessions
 * - {@link WorkoutSessionExerciseService} - Used to calculate SFR and recovery recommendations
