When parsing documents with long titles or section headings (e.g., shell scripts whose comments are treated as markdown headings), the generated filenames could exceed the OS 255-byte limit, causing 'file name too long' errors. Fix: - _sanitize_for_path: append SHA-256 hash suffix when truncating, ensuring uniqueness across different long titles that share a common prefix - _generate_merged_filename: apply same hash-based truncation - _generate_filename (downloader): apply same pattern - VikingFS._uri_to_path: add safety net that shortens any path component exceeding 255 bytes, guaranteeing no filesystem error regardless of which parser produced the URI Fixes volcengine#171

#comments are treated as markdown headings).When filenames exceed the OS limit, they are now truncated with a SHA-256 hash suffix to preserve uniqueness.
