Restore missing Go module checksums for go-ethereum metrics transitive deps

[Copilot]

The build was failing across multiple packages because the module graph referenced github.com/ethereum/go-ethereum/metrics@v1.16.7 without corresponding checksum coverage for its transitive CPU metrics dependency (github.com/shirou/gopsutil/cpu). This caused go test setup failures before package compilation.

• Dependency graph synchronization

  • Updated module metadata to align with go-ethereum metrics transitive requirements.
  • Added the missing indirect module entries required by that chain in go.mod.

• Checksum completion

  • Added the missing go.sum entries for:
    • github.com/shirou/gopsutil
    • platform-specific transitive dependencies (wmi, go-ole, go-sysconf, numcpus, and related x/sys go.mod checksums)

• Scope

  • No application logic changes.
  • No API or behavioral changes; this is strictly module/dependency metadata correction.

require (

    github.com/tklauser/go-sysconf v0.3.12 // indirect
    github.com/tklauser/numcpus v0.6.1 // indirect
