💡 What: Applied @functools.lru_cache to _compiled_context_lexicon in openmed.clinical.context.
🎯 Why: The function repeatedly compiled the same regex patterns for clinical context resolution on every document or span lookup, which was a significant performance bottleneck.
📊 Impact: >90x speedup for the specific function and ~3x end-to-end reduction in overhead during context processing for large batches of spans.
🔬 Measurement: Verified using a local benchmark script timing 100 loops of scan_context_cues with and without the LRU cache.
