- Introduced `_step_neighbors_at_index` to safely retrieve neighboring steps without causing IndexErrors, improving robustness in gap fill specifications.
- Updated `collect_gap_fill_specs` to utilize the new neighbor retrieval function, ensuring safe access to adjacent steps during gap fill processing.
- Enhanced rematch logic in `_run_roadmap_rematch_loop` to incorporate `max_rematch_rounds`, allowing for controlled iterations during roadmap rematching.
- Improved handling of unfilled roadmap slots in `collect_rematch_slot_indices`, ensuring accurate identification of gaps in the progression path.
- Added tests to validate the new gap fill handling and rematch logic, ensuring reliability in path suggestion features.
- Improved off-topic step handling by incorporating roadmap major step indices for better indexing and detection.
- Refactored `collect_gap_fill_specs` to streamline the insertion logic for off-topic steps, ensuring correct placement based on major step indices.
- Introduced `_normalize_roadmap_steps_coverage` function to standardize roadmap steps coverage, enhancing the handling of missing slots.
- Added `prune_stripped_after_rematch` function to clean up stripped off-topic steps after rematching, improving the overall rematching process.
- Updated tests to validate new rematching and off-topic handling features, ensuring robustness against edge cases.
- Incremented application version to reflect these updates.
- Introduced `auto_rematch_after_qa` parameter in `ProgressionPathSuggestRequest` to enable automatic rematching after quality assurance checks.
- Refactored roadmap slot matching logic to improve clarity and functionality, renaming `_build_steps_roadmap_first` to `_match_roadmap_slot`.
- Added `_with_roadmap_major_index` utility to streamline off-topic step detection by incorporating roadmap major step indices.
- Enhanced off-topic detection logic to utilize the new utility for improved clarity in identifying mismatches and exclusions.
- Incremented application version to reflect these updates.
