Note

High Risk
Large dependency churn plus a Go toolchain version bump (go 1.18 → 1.25.6) could introduce build/CI breakages and subtle runtime behavior changes (notably around grpc, x/crypto, and other transitive upgrades).

Overview
Updates the module’s dependency set, most notably bumping github.com/bufbuild/buf from v1.9.0 to v1.66.1, which pulls in a new set of Buf-related transitive deps.

Also upgrades the declared Go version (go 1.18 → go 1.25.6) and refreshes several core libraries (e.g., google.golang.org/grpc, golang.org/x/*, google.golang.org/protobuf, cobra, testify, rs/cors), with corresponding go.sum rewrites.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
