fix: add unnecessary negative contrast detection to voice linting

- New lint check: 'doesn't just X. They Y' pattern (Claude rhetorical crutch)
- Fixed last instance in judgment essay: 'doesn't just lose income. They lose'
  → 'loses the acknowledgment... The income is secondary.'
- Updated voice-check skill dimension 2 with the pattern description
- Updated AGENTS.md with the new check
- Tightened regex to avoid false positives on legitimate 'isn't only' framing
