Groups scanned markdown files into a nested directory tree.
Files under node_modules, .git, or dist directories are excluded at any depth. Directories sort
before files and each group sorts alphabetically. When maxDepth is given, entries deeper than the
limit are cut from the rendering (the affected directory is flagged truncated); statistics
computed from the scanned files are unaffected because they never read this tree.
