Refactor indexing pipeline and partition path resolution

Invert dependencies by moving partition path primitives to a dedicated module and updating the index crate accordingly. Reshape the partition router to accept a mutable index reference, enabling chainable configuration and resolving lifetime issues with explicit drops. Shift orchestration logic from the index crate to the CLI, replacing monolithic scatter calls with discrete dereplication and counting steps. Introduce a generic progress callback API to decouple rate calculation from UI rendering, and correct file I/O paths to route layer-0 artifacts under the partition index directory.
