chore: bump longhorn-engine and longhorn-spdk-engine dependencies

[Copilot]

Updates longhorn-engine and longhorn-spdk-engine to specific upstream commits.

Changes

• github.com/longhorn/longhorn-engine → c391dbfb553089894c8959f350e8e4e3b5c30fa1
• github.com/longhorn/longhorn-spdk-engine → 460b2e7c5437ad02d2b9914b4b74361a76d7fe5e

Notable

Upstream changes include adding grpc.WithDisableServiceConfig() to gRPC client connections, which prevents DNS flooding in Kubernetes environments.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.google.com
  • Triggering command: /update-job-proxy /update-job-proxy orn/sparse-tools-c l/linux_amd64/cocore.quotePath=false 0.1-go1.25.6.lindiff -o nager/vendor/k8s--irreversible-delete nager/vendor/k8s-U0 0.1-go1.25.6.lin77db8de4d8e6afce744c6e8e4f2fe60ae0c24b8e plyconfigurationgit plyconfigurationrev-parse t 0.1-go1.25.6.linux-amd64/pkg/too-trimpath .cfg�� k/longhorn-instance-manager/long-p 6502256/b150/ rg/toolchain@v0.0.1-go1.25.6.lin-lang=go1.25 ation_client.go r.go l/linux_amd64/co-c rg/toolchain@v0.0.1-go1.25.6.lin-lname (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Update go module dependencies in longhorn/longhorn-instance-manager on branch master as follows:

• Bump github.com/longhorn/longhorn-engine to commit c391dbfb553089894c8959f350e8e4e3b5c30fa1.
• Bump github.com/longhorn/longhorn-spdk-engine to commit 460b2e7c5437ad02d2b9914b4b74361a76d7fe5e.

After updating the versions, run go mod tidy and go mod vendor to refresh module metadata and vendored dependencies. Ensure resulting go.mod, go.sum, and vendor/ changes are included.

Use a conventional commit style for the commit/PR title (e.g., chore:).
