💡 What: Replaced the O(N*M) nested loop (matching exercises to solutions) with an O(N) precomputed hash map in evolutia/material_extractor.py and evolutia/rag/rag_indexer.py.
🎯 Why: Iterating over all solutions for every single exercise introduces a massive bottleneck as the number of exercises and materials grows. Precomputing a dictionary avoids quadratic complexity.
📊 Impact: Benchmark showed a ~100x to ~200x speedup for processing 5000 exercises.
🔬 Measurement: Verified that tests pass, functionality is identical (it preserves the original break behavior by keeping the first matched solution), and no regressions were introduced.

- Precomputes solutions map per material to turn O(N*M) list scan into O(N) dict lookup.
- Handled `break` parity by preserving first match for labels.
- Applied optimization to `MaterialExtractor.get_all_exercises` and `RAGIndexer.index_materials`.
- Formatted and linted modified files.

Pull request overview

This PR aims to improve performance when matching exercises to their solutions by replacing per-exercise nested scans over solutions with a per-material precomputed hash map (preserving “first match wins” semantics).

Changes:

  • Refactor exercise→solution matching to use a solutions_map dict in MaterialExtractor.get_all_exercises.
  • Refactor exercise→solution matching to use a solutions_map dict in RAGIndexer.index_materials.
  • Minor formatting/housekeeping updates (and notes update in .jules/bolt.md).
