Inspector performance monitoring (#631)

The Inspector now includes configurable performance monitoring for
setter calls, which helps identify potential performance bottlenecks

Performance monitoring settings are part of the `RendererMainSettings`
and can be configured via the `inspectorOptions` property:

```typescript
import { RendererMain, Inspector } from '@lightningjs/renderer';

const renderer = new RendererMain({
  appWidth: 1920,
  appHeight: 1080,
  inspector: Inspector, // Enable inspector
  inspectorOptions: {
    enablePerformanceMonitoring: true,  // Enable/disable setter performance monitoring (default: true)
    excessiveCallThreshold: 50,         // Warning threshold for setter calls (default: 100)
    resetInterval: 3000,                // Reset interval in milliseconds (default: 5000)
    enableAnimationMonitoring: true,    // Enable/disable animation monitoring (default: true)
    maxAnimationHistory: 500,           // Maximum animations to keep in history (default: 1000)
    animationStatsInterval: 15,         // Print animation stats every 15 seconds (default: 0 - disabled)
  }
}, 'app');
```

## Settings

### Setter Performance Monitoring

### `enablePerformanceMonitoring`
- **Type**: `boolean`
- **Default**: `true`
- **Description**: Enable or disable performance monitoring for setter
calls

### `excessiveCallThreshold`
- **Type**: `number`
- **Default**: `100`
- **Description**: The number of setter calls within the reset interval
that triggers a performance warning

### `resetInterval`
- **Type**: `number`
- **Default**: `5000` (5 seconds)
- **Description**: Time interval in milliseconds after which setter call
counters are reset

### Animation Monitoring

### `enableAnimationMonitoring`
- **Type**: `boolean`
- **Default**: `true`
- **Description**: Enable or disable animation monitoring and statistics
tracking

### `maxAnimationHistory`
- **Type**: `number`
- **Default**: `1000`
- **Description**: Maximum number of completed animations to keep in
history for analysis

### `animationStatsInterval`
- **Type**: `number`
- **Default**: `0` (disabled)
- **Description**: Automatically print animation statistics to console
every X seconds (0 to disable)

## Animation monitor Output

When enabled, you'll see output like this every X seconds:

```
🎬 Animation Stats: 3 active, 42 completed, 850ms avg duration
```

## Warning Output

When the threshold is exceeded, you'll see console warnings like:

```
🚨 Inspector Performance Warning: Setter 'x' called 75 times in 2000ms on node 123
🚨 Inspector Performance Warning: Setter 'x' called 125 times in 2000ms on node 123 (continuing...)
```

This helps identify nodes and properties that might benefit from
optimization, such as reducing animation frequency.
