Revamp the wiki taxonomy planning process to assign coherent directory paths to entity/concept pages in a single pass, ensuring consistent reuse of existing folders. This change eliminates the need for per-page category assignments during the reduce phase, preserving user-curated categories. Consolidate category path parsing and deduplication into a shared utility, improving consistency across the service and repository layers. Update related functions and tests to reflect these changes, ensuring efficient handling of category paths in the wiki ingestion process.
