- Replaced `crypto.createHash` with Node 22's one-shot `crypto.hash` API. - Replaced slow `.toFixed(8)` rounding with fast `Math.round(x * 1e8) / 1e8` (~12x faster). - Optimized `syntheticVector` and `normalizeVector` using manual for-loops and pre-allocated arrays. - Measured ~4x speedup in synthetic vector generation (8.8ms -> 2.1ms per vector).

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

💡 What
Optimized the
@jeanbot/aipackage's synthetic vector generation and normalization logic.🎯 Why
Synthetic vector generation is a deterministic but computationally expensive fallback for embeddings. The original implementation relied on high-overhead array methods and string-based numerical rounding, which created a bottleneck.
📊 Impact
.toFixed(8)withMath.roundmath).🔬 Measurement
Benchmarks were run using a local script generating 100 synthetic vectors.
Baseline: ~8.8ms/vector.
Optimized: ~2.1ms/vector.
Correctness verified via L2 magnitude checks and existing
