**Title:** Implement mcpctl describe proxymodel Command

**Status:** cancelled

**Dependencies:** 78 ✓

**Priority:** medium

**Description:** Add CLI command to show detailed information about a specific proxymodel including full stage configuration.

**Details:**

Create `src/cli/src/commands/describe-proxymodel.ts`:

```typescript
import { Command } from 'commander';
import { loadProxyModels } from 'mcplocal/proxymodel/loader';
import { stringify as yamlStringify } from 'yaml';

export function registerDescribeProxymodel(program: Command): void {
  program
    .command('describe proxymodel <name>')
    .description('Show detailed information about a proxymodel')
    .action(async (name: string) => {
      const models = await loadProxyModels();
      const model = models.get(name);
      
      if (!model) {
        console.error(`Proxymodel '${name}' not found`);
        process.exit(1);
      }
      
      console.log(`Name: ${model.metadata.name}`);
      console.log(`Source: ${isBuiltIn(name) ? 'built-in' : 'local'}`);
      console.log(`Controller: ${model.spec.controller ?? 'gate'}`);
      console.log(`Cacheable: ${model.spec.cacheable ? 'yes' : 'no'}`);
      console.log(`Applies to: ${(model.spec.appliesTo ?? ['prompts', 'toolResults']).join(', ')}`);
      console.log('');
      console.log('Stages:');
      for (const stage of model.spec.stages) {
        console.log(`  - ${stage.type}`);
        if (stage.config) {
          console.log(`    config:`);
          for (const [k, v] of Object.entries(stage.config)) {
            console.log(`      ${k}: ${JSON.stringify(v)}`);
          }
        }
      }
    });
}
```

**Test Strategy:**

CLI test: `mcpctl describe proxymodel default` shows expected output. Test with proxymodel that has stage configs, verify all fields displayed correctly.
