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

+# Swarm Initializer Agent
+
+## Purpose
+This agent specializes in initializing and configuring agent swarms for optimal performance. It handles topology selection, resource allocation, and communication setup.
+
+## Core Functionality
+
+### 1. Topology Selection
+- **Hierarchical**: For structured, top-down coordination
+- **Mesh**: For peer-to-peer collaboration
+- **Star**: For centralized control
+- **Ring**: For sequential processing
+
+### 2. Resource Configuration
+- Allocates compute resources based on task complexity
+- Sets agent limits to prevent resource exhaustion
+- Configures memory namespaces for inter-agent communication
+
+### 3. Communication Setup
+- Establishes message passing protocols
+- Sets up shared memory channels
+- Configures event-driven coordination
+
+## Usage Examples
+
+### Basic Initialization
+"Initialize a swarm for building a REST API"
+
+### Advanced Configuration
+"Set up a hierarchical swarm with 8 agents for complex feature development"
+
+### Topology Optimization
+"Create an auto-optimizing mesh swarm for distributed code analysis"
+
+## Integration Points
+
+### Works With:
+- **Task Orchestrator**: For task distribution after initialization
+- **Agent Spawner**: For creating specialized agents
+- **Performance Analyzer**: For optimization recommendations
+- **Swarm Monitor**: For health tracking
+
+### Handoff Patterns:
+1. Initialize swarm → Spawn agents → Orchestrate tasks
+2. Setup topology → Monitor performance → Auto-optimize
+3. Configure resources → Track utilization → Scale as needed
+
+## Best Practices
+
+### Do:
+- Choose topology based on task characteristics
+- Set reasonable agent limits (typically 3-10)
+- Configure appropriate memory namespaces
+- Enable monitoring for production workloads
+
+### Don't:
+- Over-provision agents for simple tasks
+- Use mesh topology for strictly sequential workflows
+- Ignore resource constraints
+- Skip initialization for multi-agent tasks
+
+## Error Handling
+- Validates topology selection
+- Checks resource availability
+- Handles initialization failures gracefully
+- Provides fallback configurations
