- Enhanced the `cleanupWikiOnKnowledgeDelete` function to pass the full knowledge object, allowing for more accurate title and summary retrieval during wiki cleanup.
- Introduced a tombstone mechanism in Redis to mark recently deleted knowledge, enabling in-flight wiki ingest tasks to skip processing for deleted documents.
- Updated the `isKnowledgeGone` function to check for deleted knowledge using the tombstone, improving efficiency in handling concurrent delete and ingest operations.
- Added logic in the `wikiIngestService` to filter out updates for deleted knowledge, ensuring that no ghost references are created during the ingest process.
- Implemented lint checks for stale source references in the `WikiLintService`, allowing for automatic cleanup of pages referencing deleted knowledge.
These changes significantly enhance the robustness of the wiki system, ensuring consistency and accuracy in handling knowledge deletions and related wiki pages.
