Function encodeYAMLNodeIndented

pkg/engine/engine.go:2049–2062

encodeYAMLNodeIndented writes node to w as 2-space-indented YAML and returns wrapped errors for both the encode and close phases. Hoisted out of applyPatchesAndRenderConfig so the close-error wrap is unit-testable via a fault-injecting writer; sister sites at engine.go:585 and :765 use the same enco

(w io.Writer, node *yaml.Node)

// is unit-testable via a fault-injecting writer; sister sites at
// engine.go:585 and :765 use the same encode+close idiom inline.
