* feat: support Helm 4 --rollback-on-failure alongside deprecated --atomic (#2712) Helm 4 renamed the `--atomic` flag to `--rollback-on-failure` (helm/helm#13629). The old flag still works under Helm 4 but is deprecated (prints a warning) and slated for removal in Helm 5. Add a `rollbackOnFailure` key to both `helmDefaults` (HelmSpec) and `releases[]` (ReleaseSpec) that emits `--rollback-on-failure`. It requires Helm 4+ (errors otherwise) and is mutually exclusive with `atomic`. Additionally, when the resolved Helm binary is v4+, an existing `atomic: true` now emits `--rollback-on-failure` instead of `--atomic`, so users are migrated off the deprecated flag automatically without any config change. On older Helm, `atomic: true` continues to emit `--atomic`. Updated the spew-based values-ID hashes in temp_test.go that change whenever ReleaseSpec gains a field (same approach as the --force-conflicts change in #2480). Closes #2712. Signed-off-by: yxxhero <aiopsclub@163.com> * test: add integration test for rollback-on-failure / atomic migration (#2712) Covers the end-to-end plumbing that unit tests cannot (real helm version detection + cluster deploy) via test/integration/run.sh: 1. atomic: true parses, deploys a ConfigMap, and emits the version-correct flag: --rollback-on-failure on Helm 4 (auto-migration of the deprecated --atomic) and --atomic on Helm 3. 2. rollbackOnFailure: true emits --rollback-on-failure on Helm 4 and is rejected with a clear Helm-4-required error on Helm 3. Flag assertions grep the `exec: helm upgrade --install` lines logged under --debug, matching flags as standalone tokens so the release name "issue-2712-atomic" cannot be confused with the "--atomic" flag. Verified locally against Helm 4.2.3: both atomic:true and rollbackOnFailure:true emit --rollback-on-failure with no --atomic.
