Lecture notes outline builder

The builder follows simple rules: markdown hash headings, short ALL-CAPS lines, short lines ending in a colon, and short numbered titles become sections; transcript timestamps like 12:30 become section markers; bullets keep their indentation; run-on paragraphs are cut into sentences. Key terms come from bold markers and definition patterns such as "is defined as". Cornell cues are templates, one question per heading and one "Define" per key term. It will miss unusual formatting, and the summary box is deliberately yours to write; reviewing the section split before you study is part of the method.
