congqixiaandGitHub 7311d450a0 enhance: bump Go dependencies to v3 modules (#49485)
Related to #49398

Bump Go module references from pkg/v2 and milvus-proto/go-api/v2 to
pkg/v3 and milvus-proto/go-api/v3 so the client tracks the Milvus 3.x
release line.

This prepares the repository for the upcoming 3.x.y release by aligning
imports, module dependencies, and proto API references with the new
major-version module paths.

// chain is the mechanism — any regression that keys by hash only, or by

// nq=0 being skipped while its score 0.8 is higher than later accepted
// rows).

// given nq, rows belonging to new groups are rejected (pk=13 in nq=0,
// pk=7 in nq=1).
//
// Per-nq isolation is validated implicitly: nq=1 starts fresh (bucket state
