file_search was confirmed unused, and these four functions were its only
implementation: create_vector_store, upload_files_to_vector_store,
add_files_to_vector_store and delete_files_from_vector_store, plus the
VECTOR_STORE_ID constant they were the only readers of.
Nothing called any of them - verified before removing - so they could not
crash anything, but they were the last references to beta.vector_stores and
beta.assistants: a sunset API that already took the whole AI cog down once
when a startup path touched it. Wiring them back up would have hit the same
404. Removing them means no path in this module can reach that API again.
54 lines gone, no behaviour change. Suite: 82 unit + 71 integration green.
