- New ml/agents/clustering.py: embed task content via nomic-embed-text (Ollama), greedy cosine clustering (threshold 0.72, max 6 clusters), graceful fallback to project-id grouping when Ollama is unreachable - focus_area v2.0.0: compute() uses semantic clusters as focus areas; adds preferred_areas InferredParam inferred from top-2 projects by task_completion count - 135 tests, all passing Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
