Lifecycle System Refactor & Logging Centralization (#56)

## ManagedBehaviour System Refactor

- **Sealed `Awake()`** to prevent override mistakes that break singleton registration
- **Added `OnManagedAwake()`** for early initialization (fires during registration)
- **Renamed lifecycle hook:** `OnManagedAwake()` → `OnManagedStart()` (fires after boot, mirrors Unity's Awake→Start)
- **40 files migrated** to new pattern (2 core, 38 components)
- Eliminated all fragile `private new void Awake()` patterns
- Zero breaking changes - backward compatible

## Centralized Logging System

- **Automatic tagging** via `CallerMemberName` and `CallerFilePath` - logs auto-tagged as `[ClassName][MethodName] message`
- **Unified API:** Single `Logging.Debug/Info/Warning/Error()` replaces custom `LogDebugMessage()` implementations
- **~90 logging call sites** migrated across 10 files
- **10 redundant helper methods** removed
- All logs broadcast via `Logging.OnLogEntryAdded` event for real-time monitoring

## Custom Log Console (Editor Window)

- **Persistent filter popups** for multi-selection (classes, methods, log levels) - windows stay open during selection
- **Search** across class names, methods, and message content
- **Time range filter** with MinMaxSlider
- **Export** filtered logs to timestamped `.txt` files
- **Right-click context menu** for quick filtering and copy actions
- **Visual improvements:** White text, alternating row backgrounds, color-coded log levels
- **Multiple instances** supported for simultaneous system monitoring
- Open via `AppleHills > Custom Log Console`
