refactor: dead-ends paper voice — first-person consistent, remove "we" constructions
Changed abstract to first-person voice: "I catalog" and "I document" instead of "We", and removed "We argue that" in favor of direct assertion "A project's vestigial features---not its failures---reveal its evolutionary trajectory". Applied VOICE.md guidelines for directness and personal conviction.
