Add documentation explaining that in Helm 4, chart hooks are processed by post-renderers in separate streams from regular templates. This allows the same resource to appear in both hooks and templates without causing duplicate-resource errors in tools like Kustomize. Signed-off-by: promptless[bot] <promptless[bot]@users.noreply.github.com>
Updates the hooks section to accurately describe Helm 4's post-render behavior: hooks and templates are sent together by default (combined strategy). Documents all three PostRenderStrategy options and recommends nohooks for Kustomize users with patches targeting template-only resources.
