MarkdownHarvester

Harvester implementation that scans Markdown source files and converts them into documentation nodes.

Harvests Markdown files under the specified root directory and converts each into a DocNode containing a display title, relative path, and generated HTML.

Skips files inside directories named "node_modules", "bin", or "obj". If a file's name is "README" (case-insensitive), its title is set to the parent directory name or "Home" for a repository root README. Files that fail to process are skipped and an error is logged.
