Pull request overview

Removes the legacy internal/kptops translators/amendments and related tests/testdata after the move from porch to kpt, keeping pkg/lib/kptops tests working with an in-process runtime.

Changes:

• Deleted the internal/kptops package and its associated testdata.
• Removed the pkg/lib/kptops/eval.go simple runtime and its unit test.
• Introduced a new test-only in-process FunctionRuntime in pkg/lib/kptops/helpers_test.go and trimmed render_test.go accordingly.

Pull request overview

Removes the now-obsolete internal/kptops implementation and its associated tests/testdata after the move away from porch, keeping pkg/lib/kptops tests self-contained.

Changes:

• Deleted the internal/kptops package (processors + registry) and all its testdata fixtures.
• Removed the pkg/lib/kptops/eval.go wrapper runtime and its unit test.
• Refactored pkg/lib/kptops tests by removing the old render golden tests and adding a lightweight in-process function runtime for remaining render-related tests.
