Enhance Stage Matching and Retrieval Logic in Planning Exercise

- Introduced `build_stage_match_brief` to create stage-specific semantic briefs, improving roadmap matching accuracy.
- Updated path retrieval logic to differentiate between general and stage-specific semantic weights, enhancing exercise relevance.
- Added support for anti-patterns and success criteria in stage matching, allowing for more nuanced exercise selection.
- Enhanced tests to validate new stage matching features and ensure correct functionality against learning goals.
- Incremented application version to reflect these updates.
