refactor: notepat paper voice — first-person consistent, remove \"this paper\" frame
Changed abstract: removed \"This paper traces\" and \"We frame\" constructions to direct \"I trace\" and direct assertion. Also fixed intro: replaced \"This paper takes\" with \"I take\". Applied VOICE.md guidelines for personal clarity and confidence.
