Refactors the ICI link scanning script into a master-worker architecture. When a physical link timeout wedges the TPU hardware queue, the worker deliberately exits, allowing the master to restart the runtime (clearing the wedge), log the failed link, and resume testing. This allows for mapping the complete set of broken links on a node rather than aborting after the first failure. Additionally deduplicates multi-core device topologies (e.g. TPU v4) down to the chip level to perfectly match optical link geometry.
