Replaces inefficient nested loops for matching exercises to solutions in `material_extractor.py` and `rag_indexer.py` with an O(N) dictionary lookup that preserves first-match behavior. This improves scaling for large lists. Formatted modified files using black and ruff. Co-authored-by: glacy <1131951+glacy@users.noreply.github.com>

Pull request overview
This PR refactors exercise→solution matching in the extraction/indexing pipeline from nested loops (O(N*M)) to dictionary lookups (O(N+M)), improving scalability when materials contain many exercises/solutions.
Changes:
- Refactored solution lookup in
MaterialExtractor.get_all_exercises()to use asolutions_dictwhile preserving first-match semantics. - Refactored solution lookup in
RAGIndexer.index_materials()similarly, avoiding repeated scans of solutions per exercise. - Applied formatting/consistency updates (quoting, wrapping, minor cleanups) in both modules.

💡 What: Refactored O(NM) nested loops in
material_extractor.pyandrag_indexer.pyinto an O(N) dictionary lookup.🎯 Why: Nested loops matching solutions to exercises degrade performance drastically as the number of exercises and solutions grows. Replacing them with a dictionary lookup ensures linear scaling and removes unnecessary computation.
📊 Impact: Reduces time complexity from O(NM) to O(N+M) for exercise-solution matching, ensuring the application remains responsive as datasets grow.
🔬 Measurement: Verified by testing locally and passing the pre-commit review. Tested against
test_markdown_parser.py,test_config_discovery.py, andtest_exercise_analyzer_cache.pyensuring regressions were not introduced.PR created automatically by Jules for task 15247401720627197240 started by @glacy
