Refactors obikindex and obikpartitionner to delegate index construction to a new layered MPHF implementation. Adds resume-safe building with abundance filtering and count persistence, while introducing a PartitionMeta struct for JSON configuration persistence. Updates OKIError to wrap layer-specific errors, replaces single-path extraction with full path collection and logging, and registers new internal dependencies across the workspace.
