refactor: goodiepal paper voice — first-person consistent, remove hedging frames
Changed abstract: removed "This paper traces" constructor to direct "I trace", and replaced "We argue that" with direct assertion. Also fixed intro: removed "This paper argues that" frame and made statement direct. Applied VOICE.md guidelines: remove qualifier phrases, use personal conviction.
