fix(ci): install librados-dev in CI runners for CGO compilation

[CodeMonkeyCybersecurity]

Summary

All CI jobs fail with fatal error: rados/librados.h: No such file or directory because go test ./pkg/... tries to compile CGO packages (cephfs, kvm) that depend on system libraries not installed in the GitHub Actions runner.

Evidence

fatal error: rados/librados.h: No such file or directory

Affects: ci-unit, ci-integration, ci-e2e-smoke

Proposed Fix

Either:

1. Install librados-dev in CI: sudo apt-get install -y librados-dev librbd-dev
2. Or use build tags to skip CGO packages in CI: go test -tags=!cgo ./pkg/...
3. Or exclude CGO packages: go test ./pkg/... -skip 'cephfs|kvm|libvirt'

Impact

CI is red on every push, which erodes trust in the CI pipeline.
