Function ComputeFrontmatterHashFromFileWithReader

pkg/parser/frontmatter_hash.go:162–178

ComputeFrontmatterHashFromFileWithReader computes the frontmatter hash for a workflow file using a custom file reader function (e.g., for GitHub API, in-memory file system, etc.) It parses the frontmatter once from the file content, then delegates to the core logic.

(filePath string, cache *ImportCache, fileReader FileReader)
