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`

+# Custom Log Console
+
+## Overview
+
+A centralized logging system with an advanced filtering console that automatically tags log entries with class and method names. Provides powerful filtering capabilities beyond Unity's default console, including multi-select filters, text search, time-range filtering, and log export.
+
+## Using the Logging System in Code
+
+All logging automatically captures the calling class and method name using `CallerMemberName` and `CallerFilePath` attributes. Simply call the static logging methods:
+
+```csharp
+using Core;
+
+public class MyClass : ManagedBehaviour
+{
+    internal override void OnManagedStart()
+    {
+        Logging.Debug("Initialization complete");
+        Logging.Info("Player spawned at position");
+        Logging.Warning("Missing configuration, using defaults");
+        Logging.Error("Failed to load required asset");
+    }
+}
+```
+
+**Output format:**
+```
+[ClassName][MethodName] Your message
+```
+
+**Available methods:**
+- `Logging.Debug(string message)` - Detailed diagnostic information
+- `Logging.Info(string message)` - General informational messages
+- `Logging.Warning(string message)` - Non-critical issues
+- `Logging.Error(string message)` - Critical errors
+
+**Note:** All logs are broadcast via the `Logging.OnLogEntryAdded` event and stored in a central buffer accessible via `Logging.GetRecentLogs()`.
+
+---
+
+## Opening the Console Window
+
+**Menu:** `AppleHills > Custom Log Console`
+
+You can open multiple independent console instances with different filter configurations to monitor separate systems simultaneously
+

+
+## Console Interface

+
+### Toolbar Controls
+
+#### 🔵 Basic Controls (Blue outline)
+- **Clear** - Clears all log entries and resets tag lists
+- **Auto-scroll** - Automatically scrolls to newest entries when enabled
+
+#### Filter Buttons (Persistent Popups)
+
+All filter buttons open persistent popup windows that remain open during multi-selection. Changes apply when you click "Apply" or dismiss with "Close".
+
+- **🔴 Classes Filter (Red outline)**
+  - Multi-select which classes to display
+  - Includes search box for quick filtering
+  - All/None quick actions
+
+- **🟢 Methods Filter (Green outline)**
+  - Multi-select which methods to display
+  - Includes search box for quick filtering
+  - All/None quick actions
+
+- **🟡 Levels Filter (Yellow outline)**
+  - Toggle Debug, Info, Warning, Error levels
+  - All/None quick actions
+
+- **⏱ Time Filter**
+  - Opens utility window with MinMaxSlider
+  - Filter logs by timestamp range
+  - Enable/disable toggle with reset option
+
+#### Search & Export
+- **Search** - Full-text search across class names, method names, and message content
+- **Export** - Save filtered logs to .txt file with timestamp
+- **Count** - Shows `filtered/total` log count
+
+---
+
+## Visual Indicators
+
+**Color Coding:**
+- White: Debug/Info (normal operation)
+- Yellow: Warning (non-critical issues)
+- Red: Error (critical failures)
+
+**Alternating Rows:** Light/dark grey backgrounds improve readability for dense log output.
+
+---
+
+## Technical Details
+
+**Event Broadcasting:**
+```csharp
+Logging.OnLogEntryAdded += (LogEntry entry) => { /* handle */ };
+```
+
+**Manual Log Retrieval:**
+```csharp
+List<LogEntry> recentLogs = Logging.GetRecentLogs();
+```
+
+**LogEntry Structure:**
+- `ClassName` - Captured from calling file path
+- `MethodName` - Captured from `CallerMemberName`
+- `Message` - User-provided message text
+- `Level` - Debug/Info/Warning/Error enum
+- `Timestamp` - Time.realtimeSinceStartup
+- `FullFormattedMessage` - Complete formatted string
