Transform webapp into Resume Branches - Git for CVs

Features:
- Complete CV version control system with branching and submission tracking
- Interactive tree visualization showing master resume, branches, and submissions
- Diff viewer for tracking changes between CV versions
- Professional landing page with Git for CVs messaging
- Modern dashboard with three-panel layout (tree, details, preview)
- ATS-safe design philosophy throughout
- Tailwind 4 configuration with professional design system

Components:
- CVTree: Interactive expandable tree for CV versions
- DiffViewer: Visual diff display with add/remove/change highlighting
- Comprehensive data models for documents, versions, patches, submissions
- Upload modal and action buttons for CV management
- Status tracking and public sharing indicators

Architecture:
- TypeScript types for complete CV management workflow
- Responsive design with proper hover states and animations
- Mock data demonstrating realistic ML Engineer and Backend Engineer branches
- Ready for FastAPI backend integration and DOCX processing

This implements the complete 'Resume Branches' vision as a modern webapp
that treats CV management like version control for documents.
