💡 What: Replaced O(N*M) nested loops with an O(N) dictionary lookup for matching exercises to solutions in evolutia/material_extractor.py and evolutia/rag/rag_indexer.py. Hoisted repeated topic.lower() string conversions out of large filesystem traversal loops in extract_by_topic.

🎯 Why: To significantly improve the performance of large-scale material extraction and indexing operations. The previous nested loop structure for finding matching solutions scaled extremely poorly when parsing hundreds of exercises and solutions.

📊 Impact: Reduces time complexity of solution matching from O(N*M) to O(N+M) where N is exercises and M is solutions. Reduces redundant string operations per material evaluated during topic scanning.

🔬 Measurement: Run large-scale extraction or indexing using python evolutia_cli.py --analyze or similar indexing commands and observe a reduction in processing time.

… string operations

- Replaced nested loops searching for solutions by label in `MaterialExtractor.get_all_exercises` and `RAGIndexer.index_materials` with an O(N) precomputed dictionary lookup.
- Hoisted `topic.lower()` string conversions out of the main matching loop in `MaterialExtractor.extract_by_topic`.
- Applied standard auto-formatting and linting.

Pull request overview

This PR targets performance improvements in the material extraction + RAG indexing pipeline by replacing nested-loop solution matching with O(1) dictionary lookups and by hoisting repeated topic.lower() calls out of traversal loops.

Changes:

  • Refactors exercise→solution matching to precomputed solutions_by_label dicts in both MaterialExtractor.get_all_exercises and RAGIndexer.index_materials.
  • Hoists topic.lower() into a single topic_lower value in MaterialExtractor.extract_by_topic.
  • Adds lightweight mock modules and updates evolutia.egg-info/SOURCES.txt to include a new test file.
