fix(docs): correct marketing skill count to 6, total to 53, codex to 48

Devin review identified two count inaccuracies:
1. Marketing skills: 7 → 6 (only 6 directories exist under marketing-skill/)
2. Codex skill entries: 47 → 48 (.codex/skills/ has 48 entries)
3. Total skills: 54 → 53 (6+18+5+2+6+12+3+1)
