fix(sync): add business-growth and finance domains, fix main branch protection

- Add business-growth and finance to SKILL_DOMAINS in sync-codex-skills.py
- Create symlinks for 5 new skills (customer-success-manager, sales-engineer,
  revenue-operations, financial-analyst, campaign-analytics)
- Update skills-index.json (42 -> 47 skills, 7 categories)
- Fix workflow to skip auto-commit on main (branch protection blocks direct
  pushes). Auto-commit only runs on dev; main gets a warning if out of sync.
