## Example Usage

### Python API
```python
import sys
sys.path.insert(0, 'lib')

# Find plugins for a task
from plugin_skill_loader import get_plugin_skill_loader
loader = get_plugin_skill_loader()
matched = loader.find_skills_for_task('review code for security')
# Returns: [code-reviewer:security_review, ...]

# Dispatch with plugin context
from dispatcher_plugin_integration import PluginAwareTaskDispatcher
dispatcher = PluginAwareTaskDispatcher()
result = dispatcher.dispatch_with_plugin_context(
    'Optimize this function',
    'my-project',
    'job-123'
)
# Returns: {job_id, plugin_context, recommendations}
```

### CLI Usage
```bash
# Find matching skills
$ luzia plugins find "simplify this code"
{
  "matched_skills": [
    {
      "skill_id": "code-simplifier:simplify_code",
      "relevance_score": 3.5,
      ...
    }
  ]
}

# Export to knowledge graph
$ luzia plugins export
{
  "status": "success",
