…#6564) ## Motivation `linera net up --kubernetes` and the in-tree `kubernetes/linera-validator` Helm chart are obsolete: validator deployment is now driven by the ArgoCD setup in `linera-infra`. The feature also carried a flaky, disabled CI job (`remote-kubernetes-net-test`) and a stack of `cli_wrappers` (helmfile/kind/kubectl/docker/local_kubernetes_net) that nothing else uses. This backports #6325 (already merged to `main`) to `testnet_conway` so the two branches do not diverge. ## Proposal Remove `linera net up --kubernetes` and everything specific to it: - the `kubernetes/linera-validator` Helm chart directory; - the `kubernetes` cargo feature and its `k8s-openapi` / `kube` / `pathdiff` / `fs_extra` deps; - `cli_wrappers/{helmfile,kind,kubectl,docker,local_kubernetes_net,util}.rs`; - `handle_net_up_kubernetes` and the `--kubernetes` CLI branch; - the `remote-kubernetes-net-test` workflow and the `kubernetes`-gated `test_case`s in `linera_net_tests.rs`. Native (`net up`) and `remote-net` paths are untouched. ## Test Plan CI. Locally on the `testnet_conway` toolchain: `cargo check -p linera-service --all-features --tests` and `cargo clippy -p linera-service --all-features --tests` both pass, `cargo fmt --check` clean. ## Release Plan - Nothing to do / These changes follow the usual release cycle. ## Links - main PR: #6325 - closes #5911 (the flaky `remote-kubernetes-net-test` reliability issue — resolved by removing the feature) - [reviewer checklist](https://github.com/linera-io/linera-protocol/blob/main/CONTRIBUTING.md#reviewer-checklist)

Motivation
linera net up --kuberneteslaunched a local KinD cluster via Helmfile to test infra config changes. Since infra now lives in ArgoCD with automated sync on merge, any change to linera-infra deploys immediately to the real clusters — testing via a local KinD cluster no longer serves a purpose.Proposal
