**Title:** Implement mcpctl delete proxymodel Command

**Status:** cancelled

**Dependencies:** 78 ✓

**Priority:** low

**Description:** Add CLI command to delete a local proxymodel YAML file (cannot delete built-ins).

**Details:**

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

```typescript
import { Command } from 'commander';
import { unlink, access } from 'fs/promises';
import { join } from 'path';
import { loadProxyModels } from 'mcplocal/proxymodel/loader';
import { getBuiltInProxyModels } from 'mcplocal/proxymodel/built-in-models';

const PROXYMODELS_DIR = join(process.env.HOME ?? '', '.mcpctl', 'proxymodels');

export function registerDeleteProxymodel(program: Command): void {
  program
    .command('delete proxymodel <name>')
    .description('Delete a local proxymodel')
    .action(async (name: string) => {
      const models = await loadProxyModels();
      const builtIns = getBuiltInProxyModels();
      
      if (!models.has(name)) {
        console.error(`Proxymodel '${name}' not found`);
        process.exit(1);
      }
      
      const filePath = join(PROXYMODELS_DIR, `${name}.yaml`);
      
      try {
        await access(filePath);
      } catch {
        if (builtIns.has(name)) {
          console.error(`Cannot delete built-in proxymodel '${name}'`);
        } else {
          console.error(`Proxymodel '${name}' file not found at ${filePath}`);
        }
        process.exit(1);
      }
      
      await unlink(filePath);
      console.log(`Deleted ${filePath}`);
      
      if (builtIns.has(name)) {
        console.log(`Note: Built-in '${name}' will still be available`);
      }
    });
}
```

**Test Strategy:**

CLI test: can delete local proxymodel, cannot delete built-in (error message), deleting local override shows note about built-in fallback.
