Add Dependencies tab to aggregator UI
- Add D3.js dependency graph visualization to backlog.jeffemmett.com - Tab switcher between Kanban and Dependencies views - Show completed toggle filter - Force-directed graph layout with pan/zoom and drag support - Color-coded nodes by status (green=done, blue=in-progress, gray=todo) - Project-specific border colors - Click to edit task, hover to highlight connections 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
