// TestLocalDependencyChartPathNormalization tests that relative chart paths in
// release dependencies (like "../chart") are normalized to absolute paths
// relative to basePath before checking if the directory exists.
// This is a regression test for issue #2596.
//
// Background: When helmfile.d/ contains multiple release files and one release
// has a local chart dependency (chart: ../chart), the dependency chart path was
// passed to DirectoryExistsAt without normalization, causing it to be resolved
// relative to the CWD instead of basePath. This made helmfile fail to detect
// the local chart and instead try to resolve it as a remote repo, resulting in
// "failed reading adhoc dependencies: no helm list entry found for repository".
