Subject: [PATCH] chore: update tasks.md with completed infrastructure work
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Progress update:
- Core Infrastructure: 13/14 tasks completed
- Direct Extraction Track: 18/18 tasks completed
- Total progress: 30/147 tasks (20.4%)

Completed major components:
✅ UnifiedDocument model with all structures
