**Title:** Implement LLMProvider Adapter

**Status:** done

**Dependencies:** 71 ✓

**Priority:** high

**Description:** Create an adapter that wraps the existing ProviderRegistry to implement the StageContext.llm interface, providing stages with a simplified LLM access API.

**Details:**

Create `src/mcplocal/src/proxymodel/llm-adapter.ts`:

```typescript
import type { LLMProvider } from './types';
import type { ProviderRegistry } from '../providers/registry';

export function createLLMAdapter(registry: ProviderRegistry, projectName: string): LLMProvider {
  return {
    async complete(prompt: string, options?: { system?: string; maxTokens?: number }): Promise<string> {
      const provider = registry.getProvider('heavy');
      if (!provider) throw new Error('No LLM provider configured');
      
      const messages = options?.system 
        ? [{ role: 'system', content: options.system }, { role: 'user', content: prompt }]
        : [{ role: 'user', content: prompt }];
      
      const result = await provider.complete({
        messages,
        maxTokens: options?.maxTokens ?? 1000,
      });
      return result.content;
    },
    
    available(): boolean {
      return registry.getProvider('heavy') !== null;
    }
  };
}
```

This adapter uses the 'heavy' tier from the existing registry, preserving the project-level LLM configuration.

**Test Strategy:**

Unit test with mocked ProviderRegistry verifying complete() calls are delegated correctly. Test available() returns false when no provider is configured. Integration test with a real provider.
