v0.2.0 - Library API + docs + examples

What's Changed

Features

  • MaramOptions for configuration (filters, formatting, threads)
  • generate/generate_to_writer for rendered output
  • collect + render/render_to_writer for separate traversal and formatting
  • run_tree_output for CLI behavior without stdout side-effects
• Writer-based formatting (write_tree, write_json, write_csv, write_plain, write_total_size, write_distribution)
• New examples: basic, json, filters, writer, all

CLI

• run_tree now internally uses run_tree_output; behavior remains unchanged

Docs
