Add Binary Market(Proposition Binary Market)

Issue #53 | State: CLOSED | Created: 2026-01-15T01:15:49Z

### Proposition Binary Market

“Will X happen?” → Yes / No

The issue is:

  1. Frontend enforces minimum 2 outcomes
  2. Backend API validates at least 2 outcomes (batch.ts:15)
  3. BatchProcessor creates a market group with multiple markets

To fix this, I need to:

  1. Add a market type selector in the frontend (Binary vs Multi-Outcome)
  2. Allow single outcome for binary markets
  3. Update backend to handle binary markets differently
