fix: HNSW index out-of-bounds and ONNX routing fallback

HNSW fix (ruvllm-wasm v2.0.2):
- Fixed panic at 12+ patterns caused by entry_point referencing
  non-existent index before pattern was pushed to array
- Added bounds checking in search_layer() as defensive measure

ONNX routing fix (ruvector v0.2.14):
- Fixed IntelligenceEngine.route() using sync embed() instead of
  async embedAsync(), causing fallback to hash embeddings
- Route now correctly uses ONNX 384-dim semantic embeddings

π.ruv.io hooks integration:
- Added SessionStart hook to sync LoRA weights from π.ruv.io
- Added Stop hook to share session summary
- Added PostToolUse[Task] hook to share successful completions
- Generated Pi key for authentication
