This commit adds comprehensive support for Helm 4 while maintaining full backward compatibility with Helm 3. The implementation includes: - Updated helm version detection to support both Helm 3 and Helm 4 - Added HELMFILE_HELM4 environment variable to control Helm version - Modified helm execution paths to handle version-specific binaries - Updated helm plugin installation to support split architecture - Helm 4: Uses split plugin architecture (3 separate .tgz files) - helm-secrets.tgz - helm-secrets-getter.tgz - helm-secrets-post-renderer.tgz - Helm 3: Continues using single plugin installation - Updated Dockerfiles, CI workflows, and core installation code - Helm 4 requires post-renderers to be plugins, not executable scripts - Created Helm plugin structure for integration tests - Updated helmfile.yaml templates to dynamically select renderer type - Added test plugins: add-cm, add-cm1, add-cm2 - Updated integration tests for Helm 3/4 compatibility - Created Helm 4 variant expected output files - Fixed test determinism issues (repo cleanup between iterations) - Added version-specific output filtering for warnings/messages - Updated workflows to test both Helm 3 and Helm 4 - Matrix testing across Helm versions - Updated helm-diff to v3.14.0 for compatibility - Updated README and docs with Helm 4 information - Added migration guidance - Updated version requirements All changes are backward compatible - existing Helm 3 users will see no behavior changes. fix: update Helm 4 lint expected output to match filtered output The grep filter removes the semver warning, so the expected output should not include it. Updated lint-helm4 files to match the filtered output (warning removed, no extra blank line). Signed-off-by: Aditya Menon <amenon@canarytechnologies.com>
