fix: Update markdown and HTML generators to use public components

Fix method calls that were missed in the previous refactoring:
- markdown_generator.py: Use contributor_tracker, statistics_collector, and hierarchy_builder
- html_output.py: Use markdown_generator and hierarchy_builder

This fixes test failures caused by calling removed facade methods.
