Phase 06 Tier 1: Complete Backend Implementation - Recovery Tracking & Swap System

COMPLETED TASKS:
✅ 06-01: Workout Swap System
   - Added swapped_from_id to workout_logs
   - Created workout_swaps table for history
   - POST /api/workouts/:id/swap endpoint
   - GET /api/workouts/available endpoint
   - Reversible swaps with audit trail

✅ 06-02: Muscle Group Recovery Tracking
   - Created muscle_group_recovery table
   - Implemented calculateRecoveryScore() function
   - GET /api/recovery/muscle-groups endpoint
   - GET /api/recovery/most-recovered endpoint
   - Auto-tracking on workout log completion

✅ 06-03: Smart Workout Recommendations
   - GET /api/recommendations/smart-workout endpoint
   - 7-day workout analysis algorithm
   - Recovery-based filtering (>30% threshold)
   - Top 3 recommendations with context
   - Context-aware reasoning messages

DATABASE CHANGES:
- Added 4 new tables: muscle_group_recovery, workout_swaps, custom_workouts, custom_workout_exercises
- Extended workout_logs with: swapped_from_id, source_type, custom_workout_id, custom_workout_exercise_id
- Created 7 new indexes for performance

IMPLEMENTATION:
- Recovery service with 4 core functions
- 2 new route handlers (recovery, smartRecommendations)
- Updated workouts router with swap endpoints
- Integrated recovery tracking into POST /api/logs
- Full error handling and logging

TESTING:
- Test file created: /backend/test/phase-06-tests.js
- Ready for E2E and staging validation

STATUS: Ready for frontend integration and production review
Branch: feature/06-phase-06

+# Performance Bottleneck Analysis
+
+## Purpose
+Identify and resolve performance bottlenecks in your development workflow.
+
+## Automated Analysis
+
+### 1. Real-time Detection
+The post-task hook automatically analyzes:
+- Execution time vs. complexity
+- Agent utilization rates
+- Resource constraints
+- Operation patterns
+
+### 2. Common Bottlenecks
+
+**Time Bottlenecks:**
+- Tasks taking > 5 minutes
+- Sequential operations that could parallelize
+- Redundant file operations
+
+**Coordination Bottlenecks:**
+- Single agent for complex tasks
+- Unbalanced agent workloads
+- Poor topology selection
+
+**Resource Bottlenecks:**
+- High operation count (> 100)
+- Memory constraints
+- I/O limitations
+
+### 3. Improvement Suggestions
