Week 1 Critical Fix #5: String allocation reduction for improved memory efficiency

## Optimization Summary
- 15 files optimized with 30+ individual string allocation reductions
- Eliminated temporary string objects in hot paths
- Replaced string-based cache keys with efficient struct keys
- Used const references and pre-allocation where appropriate

## High-Impact Optimizations

### 1. LineOfSightManager.cpp (2 optimizations)
- **CRITICAL**: Replaced string-based cache keys with LoSCacheKey struct
  - Eliminates 3 string allocations per cache lookup (to_string + concatenation)
  - Uses FNV-1a hash for efficient struct hashing
  - Affects every LoS check in combat (hot path)
- Fixed exception message construction

### 2-5. Combat Managers (4 files, 4 optimizations)
- TargetSelector.cpp: Exception message optimization
- InterruptManager.cpp: Exception message optimization
- KitingManager.cpp: Exception message optimization
- All avoid unnecessary std::string(e.what()) construction

### 6-7. AI Core (2 files, 3 optimizations)
- BotAI.cpp: const& for GetName() and strategy->GetName()
  - Avoids copies in debug logging and strategy registration
- LeaderFollowBehavior.cpp: const& for bot->GetName()

### 8. BotPerformanceMonitor.cpp (2 optimizations)
- Pre-allocation for spell cast context strings
- Pre-allocation for alert message construction

### 9-10. Session & Commands (2 files, 2 optimizations)
- BotSession.cpp: Pre-allocated phase list construction
- PlayerbotCommands.cpp: Exception message optimization

### 11. QuestHubDatabase.cpp (3 optimizations)
- Map name construction
- Hub name generation
- Creature list building with pre-allocation

### 12. InstanceCoordination.cpp (2 optimizations)
- Encounter information string
- Loot decision string construction

### 13. BotCharacterCreator.cpp (2 optimizations)
- Character name generation with pre-allocation
- Character limit error message

### 14. BotLevelDistribution.cpp (3 optimizations)
- Config key construction with pre-allocation
- Alliance bracket name construction
- Horde bracket name construction

### 15. PlayerbotMigrationMgr.cpp (2 optimizations)
- CREATE TABLE SQL construction
- SELECT query construction

### 16. InteractionManager.cpp (3 optimizations)
- Interaction type logging
- State transition logging
- Recovery attempt logging

## Performance Impact
- Reduces memory allocations in combat hot paths
- Eliminates redundant string copies in frequently-called functions
- Improves cache efficiency with struct-based keys
- Reduces fragmentation from temporary string objects

## Pattern Changes
BEFORE:
```cpp
std::string key = "prefix_" + std::to_string(id);
std::string name = obj->GetName(); // Copy
result.msg = "Error: " + std::string(e.what());
```

AFTER:
```cpp
std::string key;
key.reserve(32);
key = "prefix_";
key += std::to_string(id);

std::string const& name = obj->GetName(); // Reference
result.msg = std::string("Error: ") + e.what();
```

## Testing
- All optimizations maintain identical behavior
- No functional changes, pure performance improvements
- Validated with existing combat AI and interaction tests

- Read/Write pool separation (3 write + 10 read connections)
- RAII connection guards (auto-return to pool)
- Health monitoring with auto-reconnect
- Prepared statement caching per connection
- Lock-free acquire/release
- Prometheus metrics integration

- Thread-local lock tracking
- Runtime violation detection with stack traces
- Static analysis tool (analyze_lock_order.py)
- 7-layer lock hierarchy definition
- CI integration for automated checks

Eliminates root causes:

- Code instrumentation examples
- Health check endpoints

Metrics tracked:
- Bot spawns, deaths, active count
- AI decision time (P50, P95, P99)
- Combat duration heatmaps
- Memory usage per component
- Database query latency

### #3: Singleton Dependency Injection (in 48KB plan)
**Priority:** MEDIUM | **Time:** 2-3 weeks | **Impact:** +60% testability

Migrate 168 singletons to DI pattern:
- ServiceContainer implementation
- Interface extraction (ISpatialGridManager, IBotSessionMgr, etc.)
- Constructor injection for BotAI
- Mock implementations for testing
- Factory pattern for service resolution

Benefits:
- Unit testable components
- Visible dependencies in constructors
- Easy mocking with GoogleMock
- Reduced coupling

Before:
```cpp
auto grid = sSpatialGridManager.GetGrid();  // Hidden dependency
```

After:
```cpp
BotAI(std::shared_ptr<ISpatialGridManager> spatialMgr);  // Explicit
```

### #7: Manager Consolidation (in 48KB plan)
**Priority:** MEDIUM-LOW | **Time:** 3-4 weeks | **Impact:** 70 → 20 managers

Consolidation roadmap:

- 20 unified managers proposed
- Clear responsibility boundaries
- Refactoring examples for ThreatCoordinator + InterruptCoordinator + DispelCoordinator → BotCombatManager

Simplifies architecture:
- Reduced indirection
- Clearer naming conventions
- Easier mental model for new developers

### #1: ClassAI Code Deduplication (in 48KB plan)
**Priority:** LOW | **Time:** 4-6 weeks | **Impact:** -30% LOC (~40,000 lines)

Data-driven rotation engine:
- Eliminate 70-85% code duplication across 13 classes × 3 specs
- Rotation DSL with SpellPriority data structures
- Generic RotationEngine replaces class-specific if/else logic
- 6,825 lines → 1,500 lines (78% reduction)

Before (175 lines per spec):
```cpp
void ArmsWarriorAI::ExecuteRotation() {
    if (CanCast(MORTAL_STRIKE)) CastSpell(MORTAL_STRIKE);
    else if (CanCast(OVERPOWER)) CastSpell(OVERPOWER);
    // ... 170 more lines
}
```

After (3 lines + data):
```cpp
const std::vector<SpellPriority> ARMS_ROTATION = {
    { MORTAL_STRIKE, 100, []() { return InMeleeRange(); } },
    { OVERPOWER, 90, []() { return HasBuff(OVERPOWER_PROC); } }
};
```

- Return BotAI's GatheringManager

IMPLEMENTATION:
- Added includes for BotSession.h and BotAI.h
- Implemented full chain: Player → WorldSession → BotSession → BotAI → GatheringManager
- Proper null checks at each step

ISSUE #5 VERIFIED: All Initialize() methods present and called
- GatheringMaterialsBridge::Initialize() ✅
- AuctionMaterialsBridge::Initialize() ✅
- ProfessionAuctionBridge::Initialize() ✅

IMPACT:
- Gathering materials bridge can now properly configure GatheringManager
- Integration between profession system and gathering system now functional
- Completes Issue #4 and #5 from audit

Task 3 Progress: 8/33 files complete (HIGH PRIORITY TrinityCore#5)

Migrated 1 MotionMaster usage to BotMovementController for tactical
positioning with validated pathfinding.

Changes:
- Added BotAI.h and PlayerBotHelpers.h includes
- Updated MovePoint() call for target position movement (line 223)

Position System Benefits:
- Validated positioning for tactical movement
- Ground validation prevents positioning errors
- Sprint support preserved for critical movement
- Proper pathfinding to optimal combat positions

Performance: No impact when disabled
