[Fix] Fix segfault due to incorrect HTML features access

The fuzzy_cmd_from_html_part() function incorrectly accessed HTML features
via part->html_features (which doesn't exist), causing segmentation faults.
Fixed to use the correct path part->html->features for accessing tags_count,
links.total_links, and max_dom_depth properties.
