The hanzo-tools-ui docs-RAG client targets api.hanzo.ai (host already
canonicalized on main). Move the paths off the residual /api/ prefix to
top-level /v1/, matching the cloud-api route rename and the openapi
v1.0.0 lock-in (no /api/ prefix):
/api/search-docs -> /v1/search-docs
/api/chat-docs -> /v1/chat-docs
/api/index-docs -> /v1/index-docs
/api/search-docs/stats -> /v1/search-docs/stats
Hard cutover, coordinated with hanzoai/cloud (productsvc + ai serve these
at /v1), universe cloud-api-v1 AUTH_PUBLIC_PATHS, hanzo-docs RAG clients,
and the openapi cloud spec.
